Shredding Vibrato
You may only play this attack if you have discarded at least two attacks from your card pool.
Mark of the Beast, Ichi no Tachi, Graceful Kabuki, Fatal Disruptor, Illusion Kick, Lunging Snake
If this card blocks an attack with Multiple, all of that card's multiple copies are discarded.
My question should be pretty obvious - will the "anti-multiple" cards' static text fulfill the requirement for Vibrato?
1. Technically, the player using Vibrato hasn't discarded the attacks from the card pool, because the static doesn't say "your opponent discards all of the multiple copies" or something like that; basically, the cards aren't being discarded due to the Vibrato player's effect(s). Thus, Vibrato CANNOT be played.
or
2. Yes, because the player is still discarding attacks from the card pool.
