Electric Seaweed + Vigor + Shilgengar, Sire of Famine + Scurry Oak

Electric Seaweed

Vigor

Shilgengar, Sire of Famine

Scurry Oak

How it works

1. Cast Electric Seaweed by paying 2.
2. When Electric Seaweed enters, it triggers.
3. Activate Electric Seaweed by tapping it, attempting to deal 1 damage to Scurry Oak, which will instead put a +1/+1 counter on it due to Vigor.
4. Scurry Oak triggers, creating a creature token.
5. Activate Shilgengar by sacrificing the creature token.
6. When the creature token dies, Electric Seaweed triggers, dealing 1 damage to each non-Wall creature your opponents control. Each non-Wall creature you control (excluding Vigor) will not be dealt damage, and will instead have a +1/+1 counter put on it due to Vigor.
7. Scurry Oak triggers, creating a creature token.
8. Resolve the Shilgengar ability.
9. Repeat from step 5.
