How AI Deck Building Works
Three simple steps to your next winning deck
Describe Your Strategy
Tell the AI what you want to build. "Aggressive red deck for Standard", "Simic ramp with big creatures", or "Control deck that beats aggro".
AI Builds Incrementally
Watch as the AI searches your collection, adds cards one by one, and validates the deck against format rules. Real-time progress, no guessing.
Review & Customize
Get a complete deck with reasoning for each choice. Swap cards, adjust the mana base, or ask the AI to iterate on the build.
