Well we already saw Ash teach Turtwig Energy Ball and Staravia Brave Bird, so I don't think we will see either of them taught another move (they could still learn one naturally). It would be nice to see Ash teach each of his Pokemon an attack this saga.
Pikachu - Signal Beam, it needs another non electric/normal attack and I can't really see him using Grass Knot (where would he get the grass from?)
Chimchar/Monferno/Infernape - Blast Burn if it makes it to Infernape, Vacuum wave if not. I would like to see him with both moves though.
Buizel/Floatzel - Aqua Tail if it evolves, Ice Punch if not.
Gliscor - Earth Power
