Trick room Triple - Water absorb
Start with Jellicent as the trick room user, Amoongus in the middle for Rage spore, and usually lapras on the other side.
As you substitute, try to keep non water absorb or storm drain pokes on outside so can heal water absor pokes with surf.
Jellicents water spout does not heal water absorb team mates, but can be effective when at full health. If able to boost up water absorb gastrodan can be effective. If amoongus survives first turn, use spore for sleep clause one sleep.
