Counters and checks — Champions M-B

Conservative BETA candidates use the 85%-100% damage range. Counter means the target never reaches an OHKO; Check ++ means it only can on a favorable roll; Check+ or Check- means both sides guarantee an OHKO, ordered by Speed; Check -- means the response only reaches an OHKO on a favorable roll. Delayed attacks, charged attacks without a guaranteed immediate condition, interruptible attacks, HP- or turn-history-dependent attacks, and forced-sequence attacks are excluded. Recoil moves may be selected as the strongest attack; if the chosen move can self-KO its full-HP user, the matchup is forced to neutral. Partial mechanics that could change the exchange are also neutralized. The fresh lead state has zero fainted allies, so Supreme Overlord receives no boost.
