Vorel of the Hull Clade

Mu Yanling

Memnarch

How it works

1. Activate Memnarch's first ability by paying 1, causing Mu Yanling to become an artifact.
2. Activate Vorel by paying and tapping it, doubling the number of loyalty counters on Mu Yanling.
3. Activate Mu Yanling's third loyalty ability by removing ten loyalty counters from it, causing you to take an extra turn after this one.
4. Repeat from step 2 each turn.
