呪文1つを対象とする。その後、コイン投げを行う。あなたがコイン投げに勝ったなら、その呪文のコントロールを得て、それの新しい対象を選んでもよい。あなたがコイン投げに負けたなら、その呪文を打ち消す。
You don't make any decisions about new targets for the spell until you win the flip.
If the target spell has damage divided as it was cast, the division can't be changed although the targets receiving that damage still can. The same is true of spells that distribute counters.
If the target spell has a variable number of targets, you can't change how many targets it has.
If you choose new targets for the target spell, the new targets must be legal.
