Mindless Automaton + Thought Reflection + Iron Man, Armored Avenger

Mindless Automaton

Thought Reflection

Iron Man, Armored Avenger

How it works

1. Activate Mindless Automaton by removing two +1/+1 counters from it, causing you to draw two cards.
2. Iron Man triggers twice, putting two +1/+1 counters on Mindless Automaton
3. Repeat.

This engine transforms Mindless Automaton from a modest automaton into a self-sustaining card-drawing powerhouse, thanks to the explosive replacement effect of Thought Reflection doubling every card you draw. As you remove two +1/+1 counters to trigger the Automaton's ability, you draw two cards instead of one, which in turn triggers Iron Man, Armored Avenger twice to replace the counters you just spent. Because Thought Reflection ensures you net a positive card advantage on each cycle while Iron Man's triggers easily replenish the cost, you can repeat this loop to draw your entire deck.
