Idiots will forever be idiots.
I dueled this guy with my Prophecy deck, he used some weird anti-meta. He sets 4, summons Fossil Dyna, and ends. I draw and summon Temperance, use Spellbook of Secrets to get Power, then Power on Temperance. I attack, and he uses Forbidden Lance...followed by another. I respond with Spellbook of Wisdom, declaring spells, and he says I cannot because he used them in the damage step...mind you, I did not declare I was even going into the damage step. He argues with me a bit, then he activates Mirror Force, since "I can chain it to wisdom because it's spell speed 2 like a quick spell".
Kill me now.
