/// Reproduction test for PL!SP-bp4-004-P (Card 560)
/// Issue: Second ability with BATON_TOUCH condition doesn't trigger correctly
///
/// Card 560 (平安名すみれ):
/// - First ability: CONSTANT - BATON_TOUCH_MOD(2) (Optional) -> SELF
/// - Second ability: ON_PLAY - AREA="CENTER", BATON_TOUCH {FILTER="GROUP_ID=3", COUNT_EQ_2}
///   -> DRAW(2); PLAY_MEMBER_FROM_DISCARD(1) {FILTER="GROUP_ID=3, COST_LE_4"}
///
/// Expected behavior:
/// - Card can be played via double baton pass (baton_touch_count = 2)
/// - When played via double baton pass from Liella! members (GROUP_ID=3),
///   the second ability should trigger: draw 2 cards and play member from discard
use engine_rust::core::logic::{CardDatabase, GameState};

/// Test double baton pass with Liella! members
/// This should trigger the second ability: DRAW(2) + PLAY_MEMBER_FROM_DISCARD
