Cavalier of Night + Phantasmal Image + Woe Strider

Cavalier of Night

Phantasmal Image

Woe Strider

How it works

1. Activate Woe Strider by sacrificing Phantasmal Image.
2. When Phantasmal Image dies, its last ability from Cavalier of Night triggers, returning itself from your graveyard to the battlefield as a copy of Cavalier of Night.
3. When Phantasmal Image enters the battlefield, its first triggered ability from Cavalier of Night triggers; choose not to sacrifice a creature.
4. Resolve the Woe Strider ability from step 1.
5. Repeat.
