Darien, King of Kjeldor + Phyrexian Vindicator + Catapult Squad + Thunder of Unity

Darien, King of Kjeldor

Phyrexian Vindicator

Catapult Squad

Thunder of Unity

How it works

1. Declare Phyrexian Vindicator as an attacker.
2. Holding priority, activate Catapult Squad by tapping two Soldiers, attempting to deal 2 damage to Phyrexian Vindicator.
3. The damage is prevented due to Phyrexian Vindicator's replacement effect. Phyrexian Vindicator triggers, dealing 2 damage to you.
4. Darien triggers, creating two 1/1 Soldier creature tokens.
5. When the Soldiers enter the battlefield, Thunder of Unity triggers twice, causing you to gain 2 life and each opponent to lose 2 life.
6. Repeat from step 2.
