Should I keep this Cresselia?

Question

It is a Cresselia with 4 perfect IVs, in HP, Att, Def, and SpA, however it has decent (22/23) SpDef IVs and has bad Speed IVs (good for trick room).
Cresselia @ Sitrus Berry
Ability: Levitate
EVs: 244 HP / 108 Def / 156 SpD
Sassy Nature
- Trick Room
- Ice Beam
- Helping Hand
- Skill Swap
This is the set I am going for, so should I keep SRing or is this a good Pokemon to keep.
Format: Battle Spot Special.

Answer 1

Personally, I would keep SRing. The Perfect 31 IV in Attack isn't needed at all, plus it increases Foul Play's power against Cresselia which isn't good. Try going for perfect IVs in HP, Def, SpA, and SpDef. Keep SR, it'll be worth it in the long run! (:
