This loop transforms Mindless Automaton into a self-sustaining engine by cleverly manipulating its counter economy. When you strip away two +1/+1 counters to draw a card, Wizard Class in its third level notices the draw and tries to place a counter back onto the Automaton—an effort amplified by Hardened Scales, which steps in to ensure three counters land instead of one. Because you net a positive counter each cycle, you can immediately cash two of them back in to draw another card, keeping the cycle spinning indefinitely while fueled by Wizard Class's removed maximum hand size.
