Solner, I'm going to give you Tox the Foonguss. Tox likes draining stuff, so he must have at all times two of Absorb, Mega Drain, Giga Drain and Ingrain. He also looves poison, so of course he must learn Toxic. Not only that, but everyone seems to be attracted to his scent, so Sweet Scent is a must and it should be used at the start of every battle. To evolve he must use Sweet Scent 15 times in the field and beat the pokemon that appear- NO RUNNING. He may forget a draining move for Sludge Bomb once he solos one of Skyla's pokemon.
Hope this isn't too hard. Good Luck
