Mentions in Other Rulings

 * Big Shield Gardna|Big Shield Gardna: A face-down "Big Shield Gardna" can only negate a Spell Card that targets 1 face-down monster, so it cannot negate "Riryoku"...


 * Spirit Reaper: If "Spirit Reaper" is targeted by "Riryoku", it is destroyed, but the increase to the other monster's ATK lasts until the end of the turn as normal.
