The set also introduces a second new mechanic called Teamwork (because, Avengers), which lets you tap your creatures to pay for additional spell effects, like HULK SMASH
It does come in tapped if you don't control a Forest, which in Mono-Green will almost never happen
I toyed with the idea of a group of characters who share a similar mechanic that let you build a multicoloured deck
Cryptic Spires is a land card that has all five mana symbols printed on it
Celes, Rune Knight On ETB, Celes, Rune Knight lets you pitch any number of cards, then draw that many plus one, and it pumps your whole team with +1/+1 counters when creatures enter from the graveyard
Bonus points for being an option for the command slot, though I wouldnt particularly recommend trying to run mono-black infect (trust me, I tried)
