How do i defeat dialgia in pokemon mystery dungeon explorers of time?

PLEASE FOLLOW - SHOWDOWN WITH DIALGA - fighting & ground type moves cause 1.4 times their normal rate of damage against primal dialga..primal dialga's roar of time is an incredibly powerful move. THROW A SLEEP OR X EYE SEED 2 buy yourself a few turns i suggest you teach your chikorita BULLET SEED so you take out dialga ASAP when you put it 2 sleep...
