Zombie World Spell/Field All monsters in each player's hand, on the field, and in the GYs become Zombie monsters.

Royal Queen of the Labrynth Castle DARK/Fiend/Xyz/Effect/Rank 8/2900 ATK/2900 DEF 2 Level 8 Fiend monsters While this card has a Level 8 "Labrynth" monster as material, it is unaffected by your opponent's activated effects.

Well, I shall take the immortal advice of a little girl from a city in Texas: "¿Por qué no los dos?"

If this card has a "Utopia" or "Utopic" Xyz Monster as material, it gains this effect. ● Unaffected by your opponent's activated effects.

Chimeratech Fortress Dragon 1 "Cyber Dragon" monster + 1+ Machine monsters Cannot be used as Fusion Material. Must first be Special Summoned (from your Extra Deck) by sending the above cards from either field to the GY. (You do not use "Polymerization".) The original ATK of this card becomes 1000 x the number of Fusion Materials used for its Special Summon. Monsters your opponent controls cannot attack, except to attack "Chimeratech Fortress Dragon". Notes: ...Not really sure what the intent of this was. I figured just expanding it to any Cyber Dragon would work. Also, gave it something defensive to make it a proper "Fortress". Next: We've tackled Vendreads a few times here. Let's go to the Vendread origin (pun intended). Someone remake Revendread Slayer.

Mystic Battleguard (OCG: Battleguard #i) EARTH/Warrior/Link/Effect/2500 ATK/LINK-3 NE, N, NW 2+ EARTH Warrior monsters All EARTH Warrior monsters you control gain 500 ATK/DEF. If you would Tribute a monster you control to Tribute Summon a Warrior monster, or activate a card effect, you can Tribute a monster(s) your opponent controls that this card points to, even though you do not control it.

(This is treated as an Xyz Summon. Transfer any materials from the target to the Special Summoned monster.) Next: I feel like AA-ZEUS is all alone. Create another Divine Arsenal Xyz with a different alternate Xyz Summon condition requiring an Xyz Monster to do something.

Utopic Warrior LIGHT/Warrior/Synchro/Effect/Level 8/2500 ATK/2000 DEF 1 Tuner + 1+ non-Tuner monsters If this card is Synchro Summoned: You can apply these effects in sequence, based on the materials used.

Control of this card cannot be switched. If this card has "Number 56: Gold Rat" as an material, it gains this effect. ● You can detach 1 material from this card; shuffle all other cards from your hand, field, GY, and that are banished into your Deck, then add 5 cards from your Deck to your hand, but during your next End Phase, you lose the Duel. Next: With the Xyz Festival of Master Duel going on, so many Fusions, Synchros, and Links got excluded. Let's make that up to some of them, shall we? Make an Xyz Monster for an archetype or deck that doesn't have any.
