Blood Artist effects are often at their strongest in sacrifice decks because they put a fast clock on the opponent
Im putting Pippin in just about all of my Commander decks that can run him and am tempted (heh) to build a deck with him as my commander
These cards make up a pretty large portion of the deck, but so long as Llanowar Elves, Steel Leaf Champion, Thrashing Brontodon, Thorn Lieutenant, and Ghalta, Primal Hunger remain viable, Mono-Green Steel Leaf Stompy has the strength behind it to survive for another season or two, depending on what Ravnica brings to us.
Love this much
The long and short of it is that its a 2/1 for G, which is a significant downgrade from Hexdrinker but a big step in allowing green to get away from mana acceleration in Cube and opening up more space for green as an aggressive color
