Mirrorform + Vela the Night-Clad

Mirrorform

Vela the Night-Clad

How it works

1. Cast Mirrorform by paying 4, causing each nonland permanent to become a copy of Vela.
2. Put all but one Vela into your graveyard due to the legend rule.
3. Each Vela you controlled triggers for each Vela that died, causing each opponent to lose 1 life for each trigger.
