Mindless Automaton + Wizard Class + Michelangelo, Weirdness to 11

Mindless Automaton

Wizard Class

Michelangelo, Weirdness to 11

How it works

1. Activate Mindless Automaton by removing two +1/+1 counters from it, causing you to draw a card.
2. Wizard Class triggers, putting two +1/+1 counters on Mindless Automaton due to Michelangelo
3. Repeat.

By taking advantage of Michelangelo, Weirdness to 11's replacement effect, every single counter-placing event is supercharged to yield an extra +1/+1 counter than normal. When you activate Mindless Automaton to draw a card, Wizard Class senses that draw at Level 3 and triggers to place a counter on a creature, which Michelangelo immediately amplifies into enough counters to keep the engine fueled. This lets you strip those counters right back off Mindless Automaton to draw yet another card, creating a self-sustaining loop of infinite card draw and infinite draw triggers.
