Simic Ramp This deck survives despite the bans that hit its powerful cards, and it even has a new staple in Uro, Titan of Natures Wrath
It was designed by Mike Neumann
Each upkeep, you put an age counter on your card, then pay the cumulative upkeep cost for each age counter on it
One of my favorites is the Crypt Ghast thing, where you make all your lands tap for more than they should, or the Cabal Coffers thing, where you have some way of generating a bunch of mana using some specific combination of cards
Lots of things can happen with a wheel effect, from Treasure generation to +1/+1 counters on the Badgersaur
It doesnt color-fix your mana to use those activated abilities, so youre probably going to copy your own creatures abilities most often
