Optimal IVs: X/31/0/31/21/31
**HP doesn't matter. 31s in attack and speed to maximize usefulness. 0 in Defense and 21 in Special Defense to keep defenses as low as possible due to PvP purposes and to counter the download ability. 31 in Special Attack because it has some special attack moves in its move pool**
Cost-saving IVs: 2x31 in Attack/Speed.
**A 21 IV difference between Defense and Special Defense with Special Defense being high
