moves with infallible accuracy are either extremely weak (e.g. aerial ace, swift, faint attack, magical leaf, shock wave, magnet bomb, and shadow punch) or are strong but have poor distribution (aura sphere, a move unique to 10 pokemon, 5 of whom are in the uber tier) or are both weak and come with -1 priority (vital throw)
the capacity that a certain move or strategy has the potential to be countered does not mean it is healthy for a metagame. double team should not be legal in any metagame at all.
