Earthbound Immortal Wiraqocha Rasca

[Premier Alexander Romanov]

You can only Special Summon "Earthbound Immortal Wiraqocha Rasca" once per turn this way. At the start of the Damage Step, if this card battles a monster: Banish that monster face-down. At the end of the Battle Phase, if this card attacked your opponent directly: Your opponent's LP becomes 100. You can only use this effect of "Earthbound Immortal Wiraqocha Rasca" once per Duel.

 

Changelog: Decided to give it a modified version of the EI basics, an inherent Summoning capability, make it capable of defeating almost any monster it battles, and give it a version of its anime effect. Fitting for the boss of the Earthbound Immortals.

Next Card: Well, if we're going into boss monster territory, let's take care of some of the worst of the boss monsters. Armityle the Chaos Phantom.

Next:

Pineapple Blast

[Dragulas]

Pineapple Blast

When a monster is Summoned, if your opponent controls more monsters than you do: Destroy as many opponent's monsters as possible so that your opponent controls the same number of monsters as you (all of your opponent's monsters if you do not control any) (your opponent chooses which of their monsters are destroyed). If the Summon was a monster to your field, you can activate this card the turn it was set. You can only activate 1 "Pineapple Blast" per turn.

 

Changes

• Can activate on any Summon

Not a bad card but powercreep got him (years ago now) Void Ogre Dragon

[Black D'Sceptyr]

Void Ogre Dragon

DARK/Dragon-Type Synchro Effect Monster/Level 8/3000 ATK/3000 DEF

 

Lore: 1 DARK Tuner + 1+ non-Tuner monsters

Cannot be destroyed by card effects while you have a Spell/Trap Card in your Spell & Trap Zones. Once per turn, if a Spell/Trap Card is activated while you have no cards in your hand (Quick Effect): You can negate the activation, and if you do, destroy that card, then this card gains 500 ATK, also you take no further damage this turn. Once per turn, if your opponent's monster declares an attack while you have no cards in your hand: You can negate that attack.

 

BD'Switchpanel:

• So essentially I gave Void Ogre back his second manga effect (the ATK gain) and tacked it to its Spell/Trap negation (more broadened now because of the next bullet point allowing you to self-trigger it yourself. 
• Also it has the effect of its accompanying anime cards Zero Gate of the Void (through damage nullification, as the original Zero Gate prevented its owner from losing the Duel while they controlled Void Ogre....)
• ...Void Shield (through some new handless attack negation...)
• ...and finally, Void Cauldron (by giving it destruction immunity while you've got an occupied Spell & Trap Zone!)

 

NEXT UP: Shien's Daredevil (let's see about giving the Shien cards a bump up)

[Darj]

Shien's Daredevil

EARTH/Warrior/Effect

Level: 4

1600/1000

If this card is Summoned: Place 2 Bushido Counters on it (max. 4). This card gains 300 ATK while it has a Bushido Counter(s) on it. If a "Six Samurai" or "Shien" card you control would be destroyed, you can remove 1 Bushido Counter from this card instead. Once per turn: You can target 1 face-up card on the field that you can place a Bushido Counter on; remove any Bushido Counters from this card, then place them on that target.

 

 

Next:

Clock Resonator

[AstralStarZero]

Clock Resonator

Level 3 EARTH Fiend Tuner/Effect
If this card is Normal Summoned, changed this card to face-up Defense Position. Once per turn, you can Special Summon 1 Level 4 or lower non-Tuner Monster from your hand, and if you do, that monster can only be used as Synchro Material this turn. A Synchro Monster Synchro Summoned using this card as Material gains this effect:

• The first time each turn this card would be destroyed by battle or card effects, it is not destroyed

ATK/1200 DEF/600

Changes:

• Switches to Def. Position on Normal Summon
• Can now Special Summon non-Tuner monster from hand, but it can only be used as Synchro Material for that turn.

Next:
Since Danger! Is going to be a thing, let's go with a bad card in an archetype that works with them.
Brron, Mad King of the Dark World

[BatMed]

Brron, Mad King of the Dark World (same stats)

When this card is Normal or Special Summoned: You can discard 1 card from your hand. Then, if the discarded card was a Level 4 or lower Fiend monster: You can Special Summon 1 Level 4 or lower "Dark World" monster from your Deck or that is banished in face-up Defense Position. If this card is discarded to the GY by a card effect: You can target 1 Level 4 or lower "Dark World" monster in your GY; Special Summon that target.

Next:

Contract With Exodia

[Krashkube]

Contract with Exodia

Normal Spell

Send 1 "Exodia the Forbidden One", "Right Arm of the Forbidden One", "Left Arm of the Forbidden One", "Right Leg of the Forbidden One" and "Left Leg of the Forbidden One" from your hand or Deck to the GY, and if you do, Special Summon 1 "Exodia Necross" from your hand, Deck or GY.

 

changes:

now sends the exodia parts to the GY rather than needing them already there

necross can be ss'd from anywhere

 

next: Exodia Necross 

[BatMed]

Exodia Necross

DARK Spellcaster | Level 7 | ATK 1800 / DEF 0

You can discard this card; add 1 "Contract with Exodia" from your Deck to your hand. Cannot be targeted or destroyed by card effects. Gains 400 ATK for each "Exodia" or "Forbidden" Spellcaster monster in the GYs. Banish this card, face-down, unless all 5 of these cards are in your GY - "Exodia the Forbidden One", "Right Arm of the Forbidden One", "Left Arm of the Forbidden One", "Right Leg of the Forbidden One" and "Left Leg of the Forbidden One".

 

changes:

• Like its ATK, the Level now is equal to the combined Levels of the "Forbidden One" monsters.
• It searches the former spell, for consistency sake.
• No longer a nomi. I think it's self explanatory? It needs all 5 pieces in your GY to stay on the field, even tho this implies that you can still summon it without "Contract with Exodia" (see card above), but let's be honest, why wouldn't you use it since it's super easy.
• Instead of being destroyed it banishes itself face-down, since it can be easily revived now (called by the grave and screams in the BG)

 

Next: Elemental HERO Inferno

[Darj]

Elemental HERO Inferno

FIRE/Warrior/Effect

Level: 8

2300/1600

"Elemental HERO Heat" + "Elemental HERO Lady Heat"

While this card is in the GY, if exactly 1 Token monster is destroyed by battle or card effect, its controller sends 2 cards from their hand to the GY. You can only use this effect of "Horseytail" once per turn.

 

ATK/400 DEF/500

 

Changes:

This card's battle position cannot be changed, except by its own effect. This card gains the following effects depending on its battle position.

* While in Attack Position: Once per turn: This card and 1 other monster on the field gain ATK equal to the combined ATK of all monsters you control, until the End Phase.

next: Number 19: Freezadon

[Draconus297]

Number 19: Freezadon

WATER - Rank 5 - Dinosaur/Xyz/Effect - 2000/2500

2 Level 5 monsters

Once per turn, if an Xyz monster you control would activate an effect by detaching Xyz Materials: You can detach 1 Xyz Material from this card instead. If an Xyz Material is detached from this card, all Xyz monsters you control gain 500 ATK (even if this card leaves the field), and cannot be targeted by your opponent's card effects until your next Standby Phase. If this card destroys your opponent's monster by battle, you can attach the destroyed monster to this card.

 

Changelog:

●Effect is now detach 1 to replace any effect that detaches Materials, so it can help Dark Rebellion Xyz Dragon, UtL, and Number 101 become better at their jobs, although the burden is still on you to make a Rank 5.

●Now provides an ATK boost and some protection every time you want to use its effect. Said boost is permanent, meaning it can slowly stack up.

●Recoups Materials through running things over in battle, giving you ample reason to actually use it in tandem with another boss that puts the pressure on. Plus, if you do use it as a companion to Volcasaurus, they can manage to be a solid threat to big boards if your opponent is lacking somehow in protection.

 

On that note, Freezadon's companion:

Number 61: Volcasaurus

[AstralStarZero]

Number 61: Volcasaurus

Rank 5 FIRE Dinosaur Xyz/Effect

2 Level 5 Monsters

Once per turn: You can detach 1 Xyz Material from this card, then target 1 face-up monster on the field; inflict damage to your opponent equal to it's ATK and if you do, destroy it, then if it was a Special Summoned Monster, you can attach it to this card as Xyz Material. If an Xyz Material(s) is detached from another Xyz monster on the field, all Xyz monsters you control gain 500 ATK and cannot be destroyed by your opponent's card effects until your next Standby Phase.

ATK/2500 DEF/1000

 

Changes:

• Reverses order of inflicting effect damage, damage happens first, then destruction
• Can destroy any monster on the field, not just opponent's monster.
• Allows reloading of Xyz Material if destroyed monster was Special Summoned
• Provides ATK boost from detaching of Material from any other Xyz Monster on the field, working in tandem with Draconus's Freezadon, and as a Counterpart, protection from destruction is guaranteed until your next Standby Phase.

Next:

Rainbow Dragon

[Flash Flyer - Sakura]

Rainbow Dragon

Armed Dragon Catapult Cannon

(As in the card that is screaming try-hard way too much in Chazz fanservice)

[Premier Alexander Romanov]

Armed Dragon Catapult Cannon
LIGHT/Machine/Fusion/Effect/Level 10/3500 ATK/3000 DEF
1 Level 8 or higher Machine Fusion Monster + 1 Level 7 or higher Dragon monster
Must first be Special Summoned (from your Extra Deck) by banishing the above cards from your field. (You do not use "Polymerization".) If this card was Special Summoned by banishing "VWXYZ - Dragon Catapult Cannon", your opponent cannot activate cards, or effects with the same name as any banished card. Once per turn: You can banish 1 card from your Deck or Extra Deck, face-up; banish all cards your opponent controls and in their GY. If this card was Special Summoned by banishing an "Armed Dragon" monster, this effect becomes a Quick Effect.

Changelog: Why make something ludicrously powerful, but ridiculously hard to Summon, when you can make it powerful, yet make it more powerful by rewarding you for going the extra mile?

Next Card: Retrain a boss monster that is incredibly hard to get out, and that hasn't been remade in this thread yet.
