"Vylon Prism" is treated as an Equip Card and equipped to "Vylon Sigma" (1800 ATK). If that "Vylon Sigma" battles an "Exploder Dragonwing" (2400 ATK), at the start of the Damage Step the Spell effect of "Vylon Prism" that increases the equipped monster's ATK by 1000 is applied immediately, and the ATK of "Vylon Sigma" becomes 2800. The effect of "Exploder Dragonwing" is a Trigger Effect that activates at the start of the Damage Step, but because the ATK of "Vylon Sigma" is higher, the effect of "Exploder Dragonwing" cannot be activated.[3]
