I'm Bringerofcake, and this is my official entrance into CGC [COMMUNITY]

Let's make an Xyz that is Xyz Summoned with other Xyz monsters that were also summoned with an Xyz summon blah blah blah

Number 100: The Key
Rank 4
DARK
Fairy/Xyz/Effect
3500/3500
2 Rank 4 Xyz Monsters (Xyz Materials on those cards are also Xyz Materials for this card)
Once per turn: you can detach an Xyz Material from this card; select and
activate one of the following effects based on the kind of card
detached:
Normal Monster: This card gains 1000 ATK until the End Phase.
Effect Monster: This card is unaffected by your opponent's card effects until the End Phase
Xyz Monster: Inflict damage to your opponent equal to the ATK of the detached monster.
Trap Card: Target 1 Spell Speed 2 card in your Graveyard: During this turn, you can activate that card at any appropriate time.

Ok, so this seems pretty ridiculous. And it is. I'm mostly toying around
with the idea of actually overlaying other Xyz monsters into new
monsters. If you hate my card, that's fine. It's supposed to be
outlandish. (Not to mention I can't think of any good effects for a
potential SIX units)

This is a community thread, so if you have any ideas, lay 'em down!

I feel intimidated by this card, but I doubt Trap Monsters will see use wth this. Also, you could post an intro as well.

except cards dont ever have spell speed in their effects :/
you could say maybe like quick play or something, idk.

Dog King, he means Quick-Play Spells and most Traps. I think.

How do I into multiquote here?
Oh well.

Striker, while I agree that Trap Monsters probably won't use this, there's still a possibility, and would thus create a ruling gap that I don't know how to fill.
