The Deck Tester is live under Tools → Deck Tester. Import any deck — a Moxfield, Archidekt, or TappedOut link, or a pasted list — and start goldfishing in seconds.
Opening hands first
Deal a 7-card hand, draw, and deal again as many times as you like, with a running average of lands in your opening hand. It's the fastest way to feel out whether your mana base keeps up with your curve before you ever sleeve the deck.
Then hit Playtest
One click drops you onto a full-screen playmat. Drag cards anywhere — there are no fixed rows, it plays like a real table. Click to tap, right-click for everything else: flip, counters, power/toughness, ability statuses with the official icons, token copies, and moves between hand, library, graveyard, exile, and the command zone. Drag a box around multiple cards to tap, move, or edit them all at once, and keep a hand on the keyboard: T tap, F flip, G graveyard, H hand, D draw, S shuffle, N next turn.
There's also a token drawer with every token your deck can create, a mana pool tracker, life and poison/energy/commander-damage counters, and a searchable library browser you can drag cards straight out of.
It's connected to everything
You'll find a Playtest button on every deck analysis, on public deck pages in Explore, and inside the Deck Builder — one click carries the deck over with your commander already in the command zone. Testing a fresh brew? Build it in the Deck Builder, check its bracket, and goldfish it without retyping a single card.
