Water Pledge

Deals damage. If used together with an ally using Fire Pledge, the ally moving first will not use a move, while the ally moving second uses Water Pledge with a power of 150, while creating a rainbow on the user's side of the field for 4 turns. The rainbow doubles the probability of secondary effects taking place on that side of the field (does not stack with Serene Grace). If used together with an ally using Grass Pledge, the ally moving second will use Grass Pledge with a power of 150, while creating a swamp on the target's side of the field for 4 turns. The swamp halves the speed of all Pokémon on that side of the field. Is unaffected by a held Water Gem.
