Stop guessing if your MTG deck is actually good
Run 1,000 simulated games in seconds and see how your deck really performs—before you ever sit down at the table.
Deck building shouldn't feel like guesswork
Most players spend hours tweaking decks without really knowing if they improved anything. You make changes, test a few hands, maybe play a game or two—but there's no clear feedback loop. Mana Lab gives you real data so you can make confident decisions.

See what's actually happening in your deck
Run 1,000 simulated games and instantly understand how consistent your draws are, whether your mana curve is working, and how quickly your deck gets online.

Identify low-impact cards, analyze opening hand quality, and get simple scores for consistency, ramp, and draw.
Test changes with confidence
Save deck versions automatically. Compare changes side-by-side. See exactly what improved—or didn't.
