How the Archidekt Playtester Works for Testing a Deck

Archidekt's playtester is a built-in "fishbowl" or solitaire mode: it lets you draw and play out a deck by yourself, without an opponent, to check how the mana, curve, and card flow actually feel. It's the right tool when you want to know whether a deck "runs" — whether you hit your land drops, find your key pieces, and have something to do each turn. It is not a rules engine and not a substitute for playing against a real opponent, so treat it as a consistency check rather than a test of whether your deck wins.

What the playtester is for

Archidekt describes it as a way to "Playtest / Fishbowl / Solitaire your deck with a modern playtester." In practice that means:

• Goldfishing — playing your deck alone to see how fast it develops.
• Checking land and ramp counts — do you reliably have the colors and amounts of mana you need?
• Testing curve and sequencing — can you use your mana efficiently turn after turn?
• Spotting dead cards — cards that sit in hand because you never have the setup for them.

Because there's no opponent, it won't tell you how the deck fares against interaction, removal, or a faster clock. Use it to validate the deck's internal machinery, then take it to real games for the rest.

Starting a playtest

The playtester lives inside the deck editor, so you don't leave the page to use it. The general flow:

1. Open the deck you want to test in the Archidekt editor.
2. Start the playtest from within the editor (the site advertises playtesting as something you do "without leaving the editor").
3. The playtester presents your deck as a library you draw from, with your hand and the battlefield laid out.

Expected result: you're looking at your own 99/100 (or 60) cards, ready to draw and play them one at a time.

Common snag: if the deck list is incomplete or contains cards the tool can't resolve, the playtest won't reflect the real deck. Fix the list first — the same editor supports importing from Arena, MTGO, and other deck lists, and adding cards by drag-and-drop or text input.

What you can do during a test

The playtester is built around the actions you'd take in a solitaire game:

• Draw cards from your library into your hand.
• Shuffle the library so each test starts from a fresh order.
• Look at your library to see what's coming.
• Move cards between hand, battlefield, graveyard, and other zones as you play them.
• Track your board state turn by turn as lands and spells come down.

This is enough to answer the questions that matter for consistency: Did I keep a hand I can actually play? Did I hit my first four land drops? Did I have a play on turn two and three? Did I find my commander or key spell by the turn I need it?

A concrete way to use it

Say you've built a Commander deck and you're unsure whether 36 lands is enough. Run the playtester several times:

1. Shuffle, draw an opening hand, and decide whether you'd keep it.
2. Play out the first five or six turns, making the land drops and casting what you can.
3. Note where it stalls — missed land drops, uncastable spells, or turns with nothing to do.
4. Shuffle and repeat a handful of times to see whether the problem is consistent or just one bad draw.

If the same failure shows up across multiple runs, that's a signal to adjust the mana base or curve. If the deck flows smoothly most of the time, the list is probably sound on its internal consistency.

Where it fits in your workflow

The playtester pairs naturally with the rest of Archidekt's editor. You can build or import a list, check its stats and prices from TCGPlayer, Card Kingdom, Cardhoarder, and Cardmarket, pull in recommendation data from Archidekt and EDHREC, and then fishbowl the result — all in one place. It's also useful before you ask for help: the site's deck help requests show lists with card counts, tags, and comments, so testing first lets you describe the specific problem ("stalls on turn four") rather than a vague one.

Bottom line: use the Archidekt playtester to check that your deck functions on its own — mana, curve, and card flow — before you spend time testing it against opponents. It won't judge your matchups, but it will quickly expose a deck that doesn't run.
