AskHandCardChoice pauses on the hand and returns the chosen card, so abilities can pay discard costs interactively. Knight of Rose, Morgana implemented: on attack, optionally discard a card for +4000 until end of turn. Test covers the full pause chain and the return to the guard step.
Added a command guard while an ability resolves, a continuation mechanism for mid-battle pauses, and TriggerAll for scanning the field. Cards: Demon Eater (soul charge at main phase start), Tyrant Deathrex (+5000 when attacking), Maiden of Libra (Counter Blast 2 and draw on hit). Three tests.
LookTopAndReorder asks top or bottom without revealing the deck. SearchDeckToCall and SearchDeckToRide wrap the search primitive; Alfred searches a Royal Paladin grade 2 or lower and calls it, Cocoa looks at the top card. Five tests.
SearchDeck hides the deck and returns matches only: none -> SearchFailedEvent and shuffle, one -> straight to the effect, several -> PendingChoice. Different arts are separate results, labelled with the printing id. Wired into Conroe, which pays Counter Blast 1 and retires itself. Four tests.
PendingChoice/ChooseCommand let effects ask the player to pick a unit. Added Counter Blast and Soul Blast cost helpers. Blaster Blade implemented for both zones with its CB2 cost and rear-guard target. Activated abilities pay rest-self and discard; Lake Maiden Lien, Gojo and Shout draw a card. Seven tests.
CardScript model with Triggered and Continuous abilities. Check Timing collects triggered abilities, orders them (turn player first, player picks the order via SelectTriggerCommand), and pauses on optional abilities (ResolveAbilityCommand). Continuous effects are recomputed on demand in EffectivePower. Scripts: Barcgal (optional call from soul), Wingal (+4000 when boosting Blaster Blade), Alfred (+2000 per Royal Paladin rear-guard). Six tests.
