Competitively, take off all moves, even if you're using Mega Blastoise or not. You should be using a Special set either way so EQ and SB would be worthless. If you are using the utility Blastoise, then use Scald|Rapid Spin|Toxic and a filler move. Maybe Ice Beam, Roar, Dragon Tail, and some even use Foresight, but that's wayyyy overrated. Mega Blastoise, however, is a pretty decent offensive Rapid Spinner. Starmie has some advantages, but Blastoise does outclasss it in a few ways. Rapid Spin|Dark Pulseand either Aura Sphere/Dragon Pulse and Scald/Water Pulse.
Ingame: Get rid of SB and EQ, but keep Surf. Hydro Pump should go too. I'm thinking maybe not Mega looking at your moves, but if so, Surf|Dark Pulse|Water Pulse|Dragon Pulse. If not Mega, then Surf|Scald|Ice Beam and either Roar/Dragon Tail.
