would be really good in Battlgrounds since you would only need 2 to make a triple. Odds are that there will be a few cards from this set which will come to battlegrounds and who knows, this might be one of them.
Let's say you play your Sidequest Righteous Cause and have a 2/5 completion. Playing Sky Claw gives you a 2/3 and two 3/2 minions, plus an extra +1/+1 to whatever else is on your field at the time. That's a pretty spicy play. Top that turn off with a Goboglide Tech the following turn and you're looking pretty good.
