Q: At the beginning of my upkeep, I use my Aven Mimeomancer to put a feather counter on Kangee, Aerie Keeper
For each die, put a number of +1/+1 counters equal to the result on each creature you control that die is touching
At the higher end of the curve, Red Deck Wins also runs the mighty [c]Goldspan Dragon[/c]
It's pretty much a slightly worse Vampiric Rites, which is one of my go-to budget sac outlets: same cmc, same mana cost activation, same payoff, but Cauldron taps to activate so can't sacrifice multiple creatures per turn unless you have other ways to untap it
Not only that, but every time he attacks it all triggers again
Then get known and start to know the cards in the format - which cards you can play at Standard format tournaments
