Thunder Wave or Ice Punch?

[Key-Ring]

Gardy already has Calm Mind, Psychic and Thunderbolt, but i'm having a hard time deciding on T-Wave or I-Punch as a final move. I dont want W-o-W due to its low accuracy <.<
And this will be primarily for the Frontier. Any help would be appreciated.

the frontier's pretty focused on sweeping, i'd go for ice punch for the pseudo-boltbeam. with that set, you cover everything for effective damage except for shedinja and magneton.
