Comment on Nightmare Manacle by Shadic-X-Hedgehog
need to have text explaining Phrexyian Mana symbols. I know them, but I'm pretty all cards with those right now have explanatory text.
Well, after a while they do leave reminder text off cards. And since Phyrexian mana is about as known as infect at this point, neither of them have reminder text on the cards I've made.
