Darien, King of Kjeldor + Phyrexian Vindicator + Catapult Squad + Haliya, Guided by Light

Darien, King of Kjeldor

Phyrexian Vindicator

Catapult Squad

Haliya, Guided by Light

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, Haliya triggers twice, causing you to gain 2 life.
6. Repeat from step 2.

This clever loop turns your own troops into a self-sustaining engine by forcing Phyrexian Vindicator to redirect damage back at yourself, triggering Darien, King of Kjeldor to marshal a fresh pair of 1/1 Soldier tokens whenever it happens. Those newly arrived tokens immediately feed Catapult Squad's tap ability to restart the whole process, while Haliya, Guided by Light passively tracks the commotion to rack up infinite life and card draw triggers.
