Zwarm
Smash Hero
I know, I actually gyro spam like that as much as possible. If they shield, I usually either gyro again, or if they're too close I laser to hit them away, then gyro their shields away.Zwarm: the gyro instantly replenishes if they sheild it, so you can just keep launching gyros until they let one one pass, its sort of an infinite gyro barrage.
I'm getting better at it. =)
