Poké-POWER: Balloon Sting
Once during your opponent’s, if Qwilfish is your Active Pokémon and is damage by an attack (even if Qwilfish is Knocked Out), you may flip a coin. If heads, the Attacking Pokémon is now Poisoned. Put 2 damage counters instead of 1 on that Pokémon between turns.
[W][W] Nerve Shot: 20
Flip a coin. If heads, the Defending Pokémon is now Paralyzed.
It shoots the poison spines on its body in all directions. Its round form makes it a poor swimmer.
