Tephraderm + Lavamancer's Skill

Tephraderm

Lavamancer's Skill

How it works

1. Activate Tephraderm by tapping it, dealing 1 damage to itself.
2. Tephraderm triggers, dealing 1 damage to itself.
3. Step 2 repeats in an infinite loop, causing the game to end in a draw.

This loop is a clever bit of rules gymnastics that forces a draw by putting Tephraderm into an unbreakable feedback loop with itself. By enchanting Tephraderm with Lavamancer's Skill, you grant the creature the ability to poke itself for 1 damage. Because Tephraderm's triggered ability fires whenever *any* creature deals damage to it, that self-inflicted 1 damage makes Tephraderm deal 1 damage right back to itself, triggering the exact same ability again and creating an infinite, mandatory loop of damage that cannot be stopped.
