A move to potentially break a lot of mons:
Marbles (Fairy): Several sizes of marbles are scattered onto the opponent’s side of the field. Whenever the opponent uses an attack that requires them to physically move from where they stand there is a 10% chance they will instead fall and deal 1/4 of the damage they would have dealt to themselves. If Spikes or Stealth Rocks are active the fallen Pokemon will take 2x the damage normally taken from them. Yes, this does include stacked Spikes at full with Rocks. Levitators and Flying Types are not affected.
Did i break it?
