Runeshell Crab and Runeshell King are not always correctly affected by debuffs
Steps to Reproduce:
1. Play Runeshell Crab.
2. During the opponent's turn, have the opponent debuff Runeshell Crab's power by at least 1 (ex.: play and activate Ghost Blades).
3. Repeat step 2.
Runeshell Crab's power remains at 2.
Runeshell Crab's and Runeshell King's buffs during the opponent's turn can be reduced by debuffs. When their buffs are not active (on the player's turn), their power is reduced to 0; when their buffs are active again (on the opponent's subsequent turns), their buffs are regained.
