Forum:Dragon's Soul Castle during the Damage Step

OK, so, Dragon's Soul Castle is fairly unique among Continuous Traps in that its Quick Effect can be used multiple times to increase a monster's ATK, and using that effect is not mandatory to activate the card itself (i.e. you choose at activation whether you want to use its effect right away or not, the same way you do with Ultimate Offering). My question is this: If you have a Dragon's Soul Castle face-down (Set during a previous turn), can you activate it during the Damage Step to increase your monster's ATK? Or do you have to first flip it face-up during the Battle Step? --78.60.146.207 (talk) 21:06, May 20, 2013 (UTC)
