Muldrotha, the Gravetide + Mu Yanling + Doubling Season

Muldrotha, the Gravetide

Mu Yanling

Doubling Season

How it works

1. Cast Mu Yanling from your graveyard by paying 4.
2. Mu Yanling enters the battlefield with ten loyalty counters due to Doubling Season.
3. Activate Mu Yanling's third loyalty ability by removing ten loyalty counters from it.
4. Mu Yanling dies as a state-based action due to having zero loyalty.
5. Resolve the Mu Yanling ability, tapping all creatures your opponent control and causing you to take an extra turn after this one.
6. Repeat each turn.
