Omnath, Locus of Rage + Mirrorform

Omnath, Locus of Rage

Mirrorform

How it works

1. Cast Mirrorform by paying 4, causing each nonland permanent you control to become a copy of Omnath.
2. Put all nonland permanents besides Omnath into your graveyard due to the legend rule.
3. Each Omnath triggers for each Omnath that died. Resolve all triggers, dealing 3 damage to any target for each trigger.
