I want to die I thought I could activate a quick-play spell the same turn you set it. I want to kms so bad rn. I was using a cerberus farming deck with anti magic arrows and stop defense(I only have one in my deck) with the perfect attack against mystic tomato and I knew marik's face down card was wheel of nightmare and I set my AMAs thinking it would be able to activate the during the battle phase and then. NOPE. I can't activate it and wheel of nightmares activates leading to my slow inevitable defeat.
Set Quick Spell cards follow the same game mechanics as Trap cards - you can't activate them the same turn you have set them. You can, however, set and activate all other Spell card types in the same turn.
Aw man, I feel you. Its so stupid cuz in actual irl game play, you're allowed to set cards during your end phrase, but with quick play spells its messed up
