So I've been using this set to some success, Its basically made to catch people off guard and has done PLENTY of damage from me, It oustalls and kills blissey easily.
Jirachi @ Leftovers
Serene Grace
Modest
252hp/252 sp atk/6 speed
- Charge Beam
- Rest
- Snore
- Energy Ball/Psychic
Charge beam with serene grace is almost guaranteed to get a +1 attack every turn it hits, Rest off damage or status ailments and snore while sleeping causing flinching 60% of the time, Energy ball is for grounds ( Should ohko about all of them after a boost from charge beam ) But psychic is a good option too since after a charge beam it can do quite a bit of damage to everything, though its walled by tyranitar and without psychic normal grassers can wall this pretty easily ( Though they'll have to rely on leech seed or HP Fire to do something significant back ).Standard blisseys ( Obviously without flamethrower! ) Can't do shit to this, Thunder-wave is recovered by sleep, toxic doesn't work on jirachi, Ice beam does about 15%, and SC toss is walled by resting.
