[Bringerofcake]

Halfway to Forever (or more accurately, Master Piece)

If you control an "Earthbound Immortal" monster: You can target 1 face-up card on the field; destroy it. You can only use this effect of "Ultimate Earthbound Immortal" once per turn. If there is a face-up Field Spell, you can activate this card from your hand.

There, more flexibility in conditions and the effect.

[morrisoni4]

Discard 1 card; Fusion Summon one monster from your Extra Deck, using monsters from your field as Fusion Material.

[morrisoni4]

Same stats.

 

Cannot be Normal Summoned/Set. You can Special Summon this card from your hand by Tributing one "Red-Eyes" monster you control, except "Red-Eyes Darkness Dragon". This card gains 300 ATK and DEF for every Dragon-Type monster in your GY. This card gains 100 ATK for every Type of monster in either player's GY, except Dragon.

A bit more flexible and powerful. Also encourages diversity, and punishes the opponent if they don't use Dragons.

 

Next: "Multiply"

Changes:

Little more versatile.

Next:
Binary Sorceress

[Dramatic Crossroad]

2 monsters, except Tokens  [Cyberse/Link/Effect] ATK/1600 LINK-2 (EARTH)
When this card is Link Summoned; You can move 1 Link Monster you control to an unoccupied  Main Monster Zone.

This card gains these effects based on the number of monsters co-linked to this card.
● 1+: When a monster co-linked to this card battles your opponent's monster and inflicts battle damage to them: You can increase the ATK of this card or a different monster this card points to by that amount of damage inflicted until the End Phase.
● 2: Once per turn (Quick Effect): You can target 2 face-up monsters you control; until the end of this turn, halve the ATK of 1 monster, and if you do, add that lost ATK to the other monster.

(i just thought LP gain is not that helpful and relevant in most cases and made an ATK snatch effect instead that you could be played around with and have synergy with the 2nd effect).

 

Next:
 Alien Skull

[morrisoni4]

"Alien Skull"

You can Tribute 1 face-up monster on your opponent's side of the field to Special Summon this card to your opponent's side of the field.

(If a monster with an A-Counter battles an "Alien" monster, it loses 300 ATK and DEF for each A-Counter during damage calculation only.)
