Pokémon TCG deck builder & playtest

Reads attack text, not just the printed number — self-damage recoil, multi-coin and Energy-count coin scaling, board/prize-count scaling (including hand-size scaling, e.g. Alakazam's Powerful Hand, and board-wide same-type Energy counts across your whole side, e.g. Hydrapple ex's Syrup Storm), drain/lifesteal, opponent-Bench splash damage (both flat "N to each" and discretionary damage-counter pools like Dragapult ex's Phantom Dive, no weakness/resistance applied, matching the card text), conditional exact-damage-counter execute attacks (Mega Absol ex's Terminal Period), and next-turn damage protection (e.g. Fly) are all applied. Weakness/resistance read each card's own printed value rather than assuming ×2/-20 (or ignored entirely when the attack's own text says so, e.g. Solrock), so older cards with different values are handled correctly too. Passive Abilities (no-Weakness, flat damage reduction/bonus) and once-per-turn activated Abilities ("Once during your turn… you may…", including typed Basic-Energy-attach-then-draw/heal templates like Teal Dance and Ripening Charge) are both read, respecting a "can't be used while affected by a Special Condition" lock and a Stadium Rule-Box ability-lock (Path to the Peak-style) when the cards say so, plus one self-sacrifice Ability shape (Cursed Blast-style: burst damage to any opponent Pokémon that unconditionally Knocks Out its own user, fired only for a Knock Out on a fair-or-better prize trade or a game-winning one). Retreat (including proactively when the Active has no usable attack, when it would overwhelmingly outclass what's on the Bench — at least double the damage and +80 flat against the real current opponent — and the engine's first 1-ply lookahead: proactively dodging a predictable lethal hit from the opponent's current board if a Bench Pokémon would survive it, using only public board information, never the opponent's hand — never retreating away from a free Knock Out, and Tool no-Retreat-Cost like Float Stone), accurate prize values (2 for V/VMAX/VSTAR/GX/ex, 3 for Tag Team GX), evolution timing (Rare Candy included), type-aware Special Energy attachment, and two triggered-Ability shapes (evolving into a Pokémon whose Ability grants a this-turn attack-damage bonus, or draws cards instead) are all modeled. Plays common Trainer effects — draw, heal, switch, search (Pokémon or basic Energy, including "up to N" quantities, either/or choices like Fighting Gong, and look-N-pick-M combined searches like Bug Catching Set), gust, energy return/acceleration, Rare Candy, Iono/N-style shuffle-and-draw (both prize-count-based and fixed-N dual-player, e.g. Judge), Escape Rope-style dual-player switch, and retrieving a Pokémon or Energy from the discard pile (Night Stretcher) — and gives Stadium/Tool cards a zone to occupy even where their specific effect isn't one of the few numeric patterns recognized. ACE SPEC's 1-per-deck rule is enforced in the Builder. The AI won't play itself into decking out (a deck-size safety margin on both Trainer and Ability-based draw/search effects) but is otherwise still a heuristic — prefers a lethal attack and the Energy type actually needed — not a search-based optimal player, so treat results as a signal about a deck's speed and consistency, not a measurement of its ceiling in skilled hands. Still not modeled: reactive on-Knockout triggered Abilities ("if this Pokémon is Knocked Out by an attack, do X" — distinct from the self-sacrifice shape above), choice-based Item text ("choose one of the following"), any attack/Ability/ Trainer text outside the patterns above (falls back to flat printed damage or is simply never played), and true simultaneous-KO tie-break rules.
