Card Tips:Micro Ray

This is a piercing deck's best friend. When you have a monster with a piercing effect, declare an attack a Face-Down DEF position monster. Wait for the Damage step (so your opponent can do much) and the Face-Down monster is flip Face-Up because face-down monsters are flipped face-up during the damage step, and activate Micro Ray. You can activate Micro Ray during the damage step because it modifies the DEF.
