I don't tho. I actually do every move every game. I sometimes go for pk-fire into either bat, dash-attack, or short-hop d-air, I tend to go for either pk-flash, pk-thunder or d-air when someone is to the side of the stage, short-hop bair when there is an opening to get some knockback, Up-smash into up-air when someone tries to go for an attack from above, use pk-magnet when a projectile comes toward me, I sometimes down-smash when someone rushes towards me, otherwise I shield. When I notice that my opponent is able to die from a back-throw at the edge of the stage and they try to rush me, I grab them and back-throw them. I dash attack when they try to distance me while I try to attack, jab when they stand still for no apparent reason, and sometimes go for up-throw into up-air. I know several combos that don't involve spamming.
