So I have a Patron Wizard, Stonybrook Schoolmaster, & Intruder Alarm in play. My opponent plays a spell and here's where the ugly gets. My opponent states that I can only tap one wizard at a time so he can respond to each ability at onse time. I was told once many, many years ago in a mtg forum that I had to tap multiple wizards at once to counter the single spell and I couldn't stagger for eveytime my opponent paid one otherwise the spell went through after the one was paid. Can someone help us clarify this in very clear legal terms.
