That's tough to say, because if you're a grass-type, you're generally weak to Tornadus-T, who is pretty common on Rain teams. I guess the best thing I could suggest would be
Celebi @ Leftovers
Trait: Natural Cure
EVs: 252 HP / 148 SDef / 108 Spd
Calm Nature (+SDef, -Atk)
- Giga Drain
- Hidden Power [Ice]
- Recover
- Perish Song
Handles rain teams pretty well, minus Tornadus-T, who you'll have to get a check for. This thing is made to tank Scalds like a pro. Natural Cure even lets it shrug off burns and such that might afflict it. It can beat most things commonly seen under rain, able to 2HKO Thundurus-T, 2HKO Breloom, 2HKO Starmie, etc. Speed EVs let it outrun standard DD Dragonite and Jolly Breloom. Giga Drain is good STAB and gets a bit of recovery, with HP Ice giving Celebi nice coverage. Recover is to keep it alive, and Perish Song is great for beating SubCM Jirachi and the like.
Remember to change Celebi's IVs to 2 Atk / 30 Def to get the most out of your EV spread, and good luck!
