Finally, power levels that mean something.
DeckCheck measures what actually matters: how fast your deck wins against real opposition. Not in a vacuum. Not based on feelings. Against three other players trying to stop you.

❌ The Old Way

"My deck's about a 7"

A subjective number that means something different to everyone.

"It's pretty strong"

Based on feelings and personal experience, not data.

"It's an expensive deck"

Price does not equal power. A costly card can still be a bad fit.

Result: Mismatched Games

Someone usually gets blown out, feels targeted, or walks away salty.

✅ The DeckCheck Way

Deck A

Wins around turn 6 in a vacuum, but any interaction slows it to a ~T8 win.

↓
Deck B

Wins around turn 8 in a vacuum, and still wins ~T8 with interaction.

↓
Conclusion: Both are power 6

PL6 = Wins around T8. Both decks are measured by the same objective, clearly defined benchmark.

Result: Balanced Matches

Everyone sits down at the table with a shared understanding of how the game should go and a fair shot to win.

Power levels = what turn can you win on?
Every deck gets measured the same way. Higher power = faster wins.

How does DeckCheck work?
The big picture.
1

Create a deck, analyze it

Add the cards one by one, bulk import, or import a list (via URL). Then, analyze it.

2

View the analysis

See your rating and read the detailed breakdown of your deck.

3

Iterate

Make your edits and use the AI tools to trim cards, fix your mana, or tune your power level. Analyze it again, anytime.

Important Note: Every analyzed deck gets a "DeckView." Think of it as a profile for that specific 100-card combination. If you change just 1 card in your deck and re-analyze it, you'll get a new DeckView for that new combination.
