1. Is it possible to use an enhancements SA more than once?
Example: player has Hidden Treasures active plays an enhancement before a blocker is presented , but then the artifact is discarded and negated by DON.
1.1 Does the enhancement go back to owner's hand and if so , can they play it again later in battle when facing an EC?
2. If player A's deck is protected from Player B's cards , can Player B shuffle a card that is in play (that is Player A's) into Player A's deck?
2.1 If a player's hand is protected from opponent's cards and the rescuer is blocked by the Goliath promo card , can they present a hero from their hand?
3. When a curse is active as an artifact , can they targeted as evil and neutral cards?
