How it works
Every card in the list is looked up in the card database and laid out as a gallery. Click any card to read its full rules text, mana cost, type, rarity and format legality — double-faced cards can be flipped. Use ← → to step through the deck.
Your deck
First hand
Draw opening hands from your deck and cycle through the possibilities — lands, curve, and keep-or-mull at a glance. Found one worth playing? Take the deck to the full goldfish table: it enforces land drops, mana, combat and triggers, and logs your kill turns against the 10,000-game Monte Carlo simulation.
Your Deck
Your Goal
Every suggested card is verified against the real card database and format legality before it reaches you.
Cards to build around
