If you can do at least a double party, then you can try this strategy I used to OHKO.
Magneton w/ Eviolite or
Magnezone w/ Wide Lens
- Reflect
- Metal Sound
- Helping Hand
Miraidon w/Magnet or Expert Belt
Modest (258 SPATK)
- Taunt
- Calm Mind
- Electro Drift
1st turn - Magneton uses Reflect to trim down damage, and Miraidon uses Taunt to prevent Swords Dance (don't use any boosting moves during this turn, as Decidueye will use a buff remover)
2nd turn - Magneton uses Metal Sound, Miraidon uses Calm Mind
3rd turn - Magneton uses Metal Sound, Miraidon user uses ATK SPATK Cheer
4th turn - Magneton uses Helping Hand on Miraidon, Miraidon uses Electro Drift
As long as you can weather the assault and get the -4 SDEF and the +1 SATK boost from CM and the cheer, Electro Drift should be a full HP shot. I tried bringing him down to -6 SDEF (3 Metal Sound turns), but it seems that doing that will trigger the shield, and also seems to leave my Magneton to be KO'ed losing the Helping Hand.
The 85% accuracy of Metal Sound is a concern, making me have to reset some tries. If you prefer the Wide Lens, then use Magnezone for the extra bulk.
