Mindless Automaton + Doubling Season + Iron Man, Armored Avenger

Mindless Automaton

Doubling Season

Iron Man, Armored Avenger

How it works

1. Activate Mindless Automaton by removing two +1/+1 counters from it, causing you to draw a card.
2. Iron Man triggers, putting two +1/+1 counters on Mindless Automaton due to Doubling Season
3. Repeat.

This clever loop relies on Doubling Season to supercharge every counter placed on Mindless Automaton, turning its card-draw engine into a self-sustaining cycle. When you remove two +1/+1 counters from Mindless Automaton to draw a card, Iron Man, Armored Avenger triggers in response to the draw and places a +1/+1 counter on the automaton. Thanks to Doubling Season's replacement effect, that single counter is doubled into two, perfectly replacing the ones you spent and allowing you to repeatedly strip counters for infinite card draw and draw triggers.
