Notes:
184+ Spe EVs outspeeds non-Scarf Rotom-Frost.
28 Spe EVs outspeeds Jolly Torterra.
The bulky spread leaves a player significantly more vulnerable to Icium Rotom-Frost, but allows for greater bulk and reliability.
The bulky spread can switch to a Calm nature and using 80 SpD EVs instead.
Ice Beam is one of Silvally-Grass's most important moves, as it allows Silvally to counter Torterra.
148 SpA EVs OHKOs 4 SpD Torterra, which makes Silvally-Grass a completely reliable Torterra counter.
U-Turn tends to suit Silvally-Grass more than Parting Shot for the increased offensive prowess and ability to chip Rotom-Frost.
U-Turn circumvents users of Soundproof and Contrary, which can trouble Silvally when using Parting Shot.
Flamethrower can be used to hurt Rotom-Frost, but Silvally-Grass suffers from 4 moveslot syndrome and prefers to counter Torterra.
