Scrap: Round. Not a valuable move and it should be replaced.
Add: Hex. I love the move, it's unique, adds to the sparse number of Ghost-type TMs, and plays well with other TMs that burn, poison, and paralyze. Another good option would be Shadow Punch, given how few physical Ghost moves there are. It'd be cool to give that distribution to some other Pokemon.
Scrap: Incinerate. Berry destruction is cool, but between Fire Blast, Flamethrower, and Overheat, there's three good fire attacks a special attacker can choose from.
Add: Power Gem. We need so many more Special Rock-type moves, and they need to be so much more available. If not Power Gem, please GF, invent a similar move.
Scrap: Quash. A neat effect but with such poor distribution, even via TM, that it isn't even worth it.
Add: Play Rough. Dazzling Gleam is a solid move with solid distribution, let's give the physical side of Fairy some love, too.
Scrap: Confide. It's pretty eh.
Add: Entrainment. Entrainment's a one-move crippler on Pokemon that depend on their abilities - a much more versatile and dangerous move than Confide. So let's give it a whirl.
Scrap: Sludge Wave. With Sludge Bomb on the roster, another move that adds only five more BP just seems redundant to me.
Add: Metronome. I know, it's kind of weird. But I think it'd be a whole lot of fun, y'know? Metronome users are very few. It had a move tutor in Gen III, but let's bring vast distribution back, if just for the hilarity of Metronome-only battles with more viable pokemon.
Also, please make Nasty Plot a TM. Every physical attacker worth their salt can either learn Swords Dance or doesn't need it, but Special Attack's biggest boosting move is rare.
Also, please bring back Dragon Pulse, Water Pulse, Giga Drain, and Avalanche.
