Hey guys I've got a couple Pokemon which I can't figure out a fourth move..

For your Breloom, if you weant a move with the same effect as Leech Seed try Giga Drain or Drain Punch. They are faster, stronger, and get you more health. Other strong, compatible TMs you could try are Hyper Beam, Solar Beam, Iron Tail, Sludge Bomb, Focus Blast, Giga Impact, Stone Edge, or Grass Knot(sometimes). Some helpful moves would be Endure, Sludge Bomb, Giga Drain/Drain Punch, or Protect. All the above moves are TMs and are compatible with Breloom, so they would all be a good choice.

For Mamoswine, if your just looking for a new moveset, go with som of these powerful attacks. First off, I would keep earthquake. Just watch out for flying type moves. You could use blizzard, which is a TM, but he learns it at lvl 56 as well. Blizzard has a 120% attack ratio, and agaist a Grass, Ground, Flying, or Dragon, plus being part Ice, would do 360% damage.The only downside is the 70% accuracy, which isnt that bad. Other possible moves would be Ice Beam, Hyper Beam, Dig, Giga Impact, Stone Edge, or Rock Climb. If you want helpful moves, throw in Toxic, Protect, or maybe Rest. Those are all compatible TMs as well.

Thats it. I hope I helped ☺ Please rate this answer so I know how I did.
