If you discard a card with madness to pay the cost of Anje’s activated ability, you’ll draw a card last. You may untap Anje before or after you choose whether to cast the discarded card, but not after you’ve chosen to cast it but before that spell resolves.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
