Flying, vigilance
Whenever you surveil, put a +1/+1 counter on Mirko.
At the beginning of your end step, you may return target creature card with power less than Mirko's from your graveyard to the battlefield with a finality counter on it. (If it would die, exile it instead.)
Surveil to grow Mirko while filling your graveyard, then each end step reanimate a creature with power less than Mirko's from your yard. You snowball Mirko's size and value engine, recurring strong utility and ETB creatures every turn for incremental advantage that overwhelms the table.
Add cheap, repeatable surveil enablers and doublers (Reflections of Littjara, Bloodchief's Thirst, fetch-style filtering) to grow Mirko quickly and reliably. Lean into low-power ETB and recursion creatures so the end-step trigger always has a strong target, and include protection like Swiftfoot Boots or counterspells to keep Mirko online. Top-end can graduate to genuine reanimation payoffs and a tight aristocrats package once Mirko regularly exceeds 4-5 power.
