Luca, Artist of Illusions

Whenever an opponent casts a creature spell, you
may exile that spell with two art counters on it.
If you do, that spell's controller creates a blue
Illusion creature token that's a copy of it, except
it has "Whenever this creature becomes the
target of a spell or ability, sacrifice it."
At the beginning of your upkeep, remove an art
counter from all spells exiled with Luca, Artist of
Illusions. Then, if any of those cards have no art
counters on them, put them on the battlefield
under
