Qwilfish

It shoots the poison spines on its body in all directions. Its round form makes it a poor swimmer.

Poke-POWER — Balloon Sting: Once during your opponent's turn, if Qwilfish is your Active Pokémon and is damaged 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.

Nerve Shot (20): Flip a coin. If heads, the Defending Pokémon is now Paralyzed.
