Psychic should slashed on the last slot of the first set, after Thunder Wave. with Toxic and Fire Blast moving to 'Moves'. Slowbro is one of the best non-Mega switch-ins to Conkeldurr, as it doesn't mind losing its item that much, so a move to 2hko it is great. Psychic also takes care of Keldeo, to which Slowbro makes a decent switch-in, while also 2HKOing Mega Venusaur on the switch, and always breaking the Sub of Sub Kyu-B, a very dangerous Pokemon to many teams. Psychic is Slowbro's best move against Rotom-W too, another very common switch-in to it. Toxic and Fire Blast are luxury moves that aren't really needed to deal with Pokemon that Slowbro wants to face.
