If there are no sp_summonable monsters in the player's hand while resolving the effect, the opponent can check the hand.
The confirm will not be applied if the player cannot sp_summon while resolving the effect.

It is not an target effect, so the attacker should be determined while resolving the effect.
The condition is changed in order to match the text "自分は攻撃モンスターの攻撃力分のダメージを受け".
