Phyrexian Vindicator + Martyrdom + Angrath's Marauders

Phyrexian Vindicator

Martyrdom

Angrath's Marauders

How it works

1. Cast Martyrdom by paying 1, targeting Phyrexian Vindicator.
2. Activate Phyrexian Vindicator by paying 0, targeting a creature.
3. Attempt to deal damage to the targeted creature. The damage will then be increased due to Angrath's Marauders, then redirected to Phyrexian Vindicator, which is then redirected back to the creature that was originally targeted.
4. Holding priority, activate Phyrexian Vindicator by paying 0, targeting the creature.
5. Repeat step 4 until all damage will be redirected to Phyrexian Vindicator.
6. Repeat from step 3.
