Forum:Using multiple cards with the text "you cannot attack during that round"?

Most likely a dumb question, but one that confused my brother and I. He is running a Volcanic deck, and a lot of his cards do things to me, at the cost of not allowing him to attack during his turn. Is he able to use as many of them as he wishes (assuming no conflicts with other abilities) during a single round, or does using one of these such abilities not allow him to repeat it with the others (as he already gave up his ability to attack.)? As an addendum to this, is he able to use such abilities if he is doing first in the duel (as the first duelist cannot attack anyways)?

Thanks in advance for any and all responses! ~Phillip Milenkov (talk • contribs) 00:59, October 2, 2016 (UTC)
