Crawdaunt admittedly is the only other user of this move that poses an offensive threat...and its slowConkeldurr also has usable bulk on both sides with Assault Vest and Mach Punch, along with semi-reliable recovery with Drain Punch. That's why it can, overall, afford to be so slow. Mawile's physical bulk is usable (moreso if it gets Intimidate off,) but her special bulk is less so. If you want Mawile to do anything without priority you need to rely solely on hitting things on the switch and taking hits overall. Yeah, Mawile can live through a hit here or there, but considering her weaknesses are so common (and you're only getting Magnet Rise up on the switch,) you're rarely in a situation where you can get more than one or two hits off. With priority Mawile can take out many threats with ease that would otherwise make you take unnecessary damage.
I'm sure Knock Off Mawile can be effective in certain situations, but I think Sucker Punch is on the whole a more useful move, and better users of Knock Off exist.
In all my battles i intended to use him for revenging, but he ended up cleaning out the entire team many timeshow is mawile's speed is it good against others because if not then i will put reuniclus on my team and trick room
is gengar a revenge killer or is he clean up
also i went to the glittering cave andi found no feroseeds does anyone have a hatched fero seed i can have
As for mawile's speed its great for trick room, but outside of it there are quite a number of defensive pokes that outspeed and cripple it if u run a TR EV spread.
Speed-creeping mawile is probably the best imo, as it outspeeds alot of slower threats while also outspeeding slower offensive threats that invest in bulk instead, allowing mawile to setup with ease behind a sub.
