Why this is Bracket 2
- Game changers · No Game Changers found.
- Mass land denial · No Mass Land Denial cards found.
- Extra turns · No Extra Turn cards found.
- Combos · Commander Spellbook estimate-bracket lookup failed and nothing was cached for this exact deck -- its signal isn't reflected in this verdict.
- Combos · Commander Spellbook find-my-combos lookup failed and nothing was cached for this exact deck -- its signal isn't reflected in this verdict.
- Notes · No signals tripped; defaulting to Bracket 2 -- Bracket 1 vs 2 is a theme judgment call this algorithm can't make on its own (see §2).
- cEDH signals · 0 free/reduced-cost interaction card(s) found (informational -- feeds the possibleCedh signal, doesn't floor the bracket on its own).
- cEDH signals · 1 cross-archetype cEDH staple(s) found, excluding anything already counted as a Game Changer (informational -- feeds the possibleCedh signal, doesn't floor the bracket on its own; this list is hand-curated and will go stale over time).
- Notes · possibleCedh signals (0/4, needs 3+): complete combos=0, avg nonland CMC=4.23, free/reduced-cost interaction=0, cEDH staples=1. Not enough independent signals agree to flag this as a likely cEDH build.
