When the Xyz Decks are Ashes, you have my permission to draw

Because apparently they are becoming a problem?

Call of Tuonela
Trap/Counter
Negate the Summon of an Xyz Monster and banish it, regardless of it's effect(s).

Ataraxia
DARK/Level 3
ATK/1250
DEF/1100
[Fairy/Effect] When this card is Summoned, you gain control of all Xyz Monsters your opponent controls.

They are? I guess i'm out of the loop.

Still, many decks can do fine without them, so I would add some effects that would work on non-xyz monsters. Maybe like this?

Call of Tuonela
Trap/Counter
Discard 1 card. Negate the Summon of a Monster and banish it, regardless of it's effect(s). If it was an Xyz monster, draw 1 card.


That might be OP'd. But it's an idea.
