While I general I'm a little wary of mixing +1/+1 and -1/-1 counters (as it can get very confusing what the size of things arethis, by the way, is where the rule about +1/+1 and -1/-1 counters canceling one another out came from), I do like how this card uses both in a contextual way that gives the card a strong flavor
Yet, one particular land card known as Mountain, Unhinged, stands above the rest for its simple yet awe-inspiring beauty and grandeur
Plus we've got Buried Alive to yoink Anger, Wonder, and a great reanimate target for example
And Green is the color of ramp and can cast this mid-game if you want to and then you can win the game with this card draw machine
All that has been revealed is that its a lot of fun, according to Mark Rosewater, but that doesnt tell us anything
