Activate Mindless Automaton's first ability by paying 1 and discarding a card, putting two +1/+1 counters on it.
Activate Mindless Automaton's second ability by removing two +1/+1 counters from it, causing you to draw a card.
The Locust God triggers, creating a 1/1 Insect creature token with flying and haste.
Activate Ashnod's Altar by sacrificing an Insect, adding CC.
Repeat.
This clever loop turns Mindless Automaton into an engine that feeds itself by leveraging its own counter manipulation alongside the replacement effect of Loading Zone. Whenever you add a counter to the Automaton, Loading Zone doubles it, immediately giving you the two counters needed to draw a card via the Automaton's second ability. Drawing that card triggers The Locust God to flood your board with a flying, hasty Insect token, which you can then sacrifice to Ashnod's Altar for a burst of colorless mana to keep the process going.
