Competitive TCG guides · Simulation · Decision intelligence
Go deeper than the decklist.
LineDepth helps competitive TCG players understand how decks actually win. Study expert pilot guides, prepare matchup plans, explore critical sequencing, simulate game states, and analyze the decisions most strongly associated with successful outcomes.
Learn the deck. Find the line. Improve every game.

From list to line
A decklist is the starting point, not the product. Every stage below is something a guide has to actually do.
Power Plays
Identify actions and sequences that are strongly associated with winning from comparable game states.
A Power Play is a contextual association, never a “best move”. The analysis layer is in development; the card beside this is a worked example on demonstration data, so you can see exactly what will and will not be claimed.
Statistical integrity
- Sample size shown on every statistic
- Confidence ranges, never bare point estimates
- Data freshness and meta-snapshot dates
- Deck-version and matchup context
- Play/draw split where it matters
- Correlation flagged as correlation
- Insufficient-data states instead of thin claims
- Demonstration data always labeled

Common alternative: holding Hook for a 6→7 conversion (−2.1pp in comparable states)
Performs poorly when the opponent holds open interaction — the kill is an effect, not a cost.
Why LineDepth
Not just decklists
Every list ships with its strategic model — roles, resources, and the conversion chain that explains the numbers.
Not just global win rates
Context first: matchup, play/draw, deck version, sample size, and confidence travel with every figure.
Not just strategy articles
Guides are interactive reference tools — probability labs, sequence steppers, boarding lanes — built to stay open during testing.
Not just a simulator
Scenarios connect back to the guide section, the testing log, and eventually the data that says which lines actually win.
New guides, as they publish
One note per published guide or major revision. No cadence, no digest, no marketing.
