'Cause fighting-type moves with much better side effects exist:
Drain Punch:
Same base power, great distribution and heals the user by half damage done
Close Combat:
A whopping 120 base power topped off with 100 accuracy. The only downside is that it lowers the users Def and SDef by 1 stage.
High Jump Kick:
130 base power and 90 accuracy without the Def and SDef drop make this an incredible move. However, in the 10% chance that you miss, you lose 50% of your max HP.
Superpower:
A move pretty much identical to CC but lowering Atk instead of SDef.
