Rulings
- Discarding a card is part of the resolution of "Bone Temple Block."
- The effects of "Bone Temple Block" happen in sequence, so if you discard "Archfiend of Gilfer," it will miss the timing on and not activate its effect.
- Born Temple Block targets the Monster Cards selected by each player.
- The turn player selects a monster first. If you activate "Bone Temple Block" during your opponent’s turn, your opponent selects first.
- If your opponent is under the effects of "Scapegoat" and cannot Special Summon, you can still activate "Bone Temple Block." In this case, only you would Special Summon a monster.
- You cannot activate "Bone Temple Block" if there are no monsters in either GY to Special Summon.
