Tevesh Szat, Doom of Fools + The Chain Veil + Ashnod's Altar + Aphetto Alchemist + Intruder Alarm

Tevesh Szat, Doom of Fools

The Chain Veil

Ashnod's Altar

Aphetto Alchemist

Intruder Alarm

How it works

1. Activate Tevesh Szat's first loyalty ability by putting two loyalty counters on it, creating two 0/1 Thrull creature tokens.
2. When the Thrulls enter the battlefield, Intruder Alarm triggers twice.
3. Resolve the first trigger, untapping all creatures.
4. Activate Aphetto Alchemist by tapping it, untapping The Chain Veil.
5. Resolve the second Intruder Alarm trigger, untapping all creatures.
6. Activate Aphetto Alchemist by tapping it, untapping target artifact or creature.
7. Activate Ashnod's Altar twice by sacrificing the two Thrull tokens, adding CCCC.
8. Activate The Chain Veil by paying 4 and tapping it, allowing you an additional activation of your planeswalkers' loyalty abilities this turn.
9. Repeat.

This clever loop uses Tevesh Szat, Doom of Fools to generate a steady stream of Thrull tokens, which immediately trip Intruder Alarm's global untap whenever they enter the battlefield. By sacrificing those tokens to Ashnod's Altar, you harvest the necessary colorless mana to fund The Chain Veil, whose activation resets Tevesh Szat's loyalty limit so he can produce more tokens. Meanwhile, Aphetto Alchemist capitalizes on the persistent untap triggers to repeatedly refresh The Chain Veil and itself, creating a self-sustaining engine of infinite mana, sacrifices, and planeswalker activations.
