I want a False Swiper to help with catching mons, and I got some options, but I don't know which to choose. I'd prefer for it to be something that can be found in ORAS, and if possible, have a status move and/or be easy to shiny hunt. Also, I'm in the post-game, so I'm okay with any Dex Nav mons.
For post-game, I would recommend Cobalion.
All in all, up to your preference, but I do think that this mon really stands out amongst the others.
I would suggest using Breloom. Here's why. Pros 1. Breloom has an amazing attack stat of 130. 2. It has access to Spore, a 100% accurate move that instantly puts the target to sleep. (In order to get spore you will have to grind a Shroomish to level 40. Make sure not to evolve it! Breloom can't learn spore. This shouldn't take that long with the xp share) 3. It can learn swords dance and good stab moves like Brick Break and Seed Bomb. Cons It has a 4x's weakness to flying. You can give it a Coba Berry to weaken the damage of flying type moves by 50%. (You can get one on Route 123 in the berry garden.)
First I'm not really that good with this kind of stuff but I'll try
I think Garchomp 1. It has an amazing Attack stat 2. You can also use Swords Dance 3.Its only weak to Ice-, Dragon- and Fairy-type 4. It has a Mega Evolution which amps up its damage output Cons 1. Mega lowers Speed 2. It's 4x weak to Ice- 3. It has no status moves (freezing, sleep, etc...) 4. It's a Dragon-type meaning it takes awhile to level up
