Goblin Bombardment

How it works

1. Cast Abby from the command zone by paying 1 plus commander tax.
2. Abby triggers, creating a number of 1/1 Cordyceps Infected creature tokens.
3. When the Cordyceps Infected tokens enter, Mana Echoes triggers that many times, adding C for each Fungus and/or Zombie you control for each trigger.
4. Resolve Abby, giving control of it to an opponent.
5. Activate Goblin Bombardment four times by sacrificing four Cordyceps Infected tokens.
6. When the Cordyceps Infected tokens die, Pitiless Plunderer triggers four times, creating four Treasure tokens.
7. Resolve the Goblin Bombardment abilities, dealing 4 damage to Abby.
8. Abby dies as a state-based action due to having 0 toughness. Choose to return it to the command zone from your graveyard.
9. Activate two Treasures by tapping and sacrificing them, adding .
10. Repeat.
