How it works
Activate Emiel by paying 3, blinking Yannik.
When Yannik leaves the battlefield, all creatures exiled with it return to the battlefield.
When Yannik enters the battlefield, it triggers, exiling another creature you control with power two or greater and putting at least two +1/+1 counters on Cryptic Trilobite.
Activate Cryptic Trilobite's first ability twice by removing two +1/+1 counters from it, adding CCCC that can only be spent to activate abilities.
