>>51983121You can't use this as the only STAB move, period. You also can't use it with choice items aside from very specific circumstances because it's total setup bait. It's basically Truant incorporated into a move.
However, if you played gen 1 competitive, you realize this move is not useless.
In the gen 1 meta, the common strategy foir offensive mons is delivering a 1-2 punch combo with Body Slam>Hyper Beam because of how it works there.
So if you use this move in the same way, it's good. If Iron Head is a 3HKO, by using Iron Head>This move then it's a 2HKO.
