Ideas for a vision

[Kaylesh]

When the new set comes out enchant him with {mirror mockery} and gods willing him then swing and create 2-3 tokens of him depending on how many of him you already have out

For those who haven't seen it its a 1 colorless, 1 blue enchantment that whenever enchanted creature attacks put a token onto the battlefield that's of the attacking creature exile it at the next end step.

Lookin at it this way it's a t3 win
T1 Breeding pool- {birds of paradise}
T2- forest {bio-visionary}
T3- {Phantasmal image}, {mirror mockery} on bio then swing and trigger fourth bio as a token. Win.

I count three... What am I missing?

Read mirror mockery incorrectly so it wouldn't have worked anyways

Yeah, token leaves at end if combat.
