The Star Store is back, and you definitely need to pick up the first three offerings:
Staple board clear for Magic. Isn't quite as prevalent in the current meta, but metas change. Great against zombies, and if nature starts moving back to wide boards instead of Big Beasts, it will be back in the limelight.
Best 7 drop nature creature according to my tier list, anyway. I had 6x from the last time it was in the store, so I made it an even 10x today (enough for 2 shadows in the future).
Every aggro War deck needs 2x. 3/4 blitz is fantastic for 4 mana, but don't sleep on the flank effect combined with it's blitz. It hits the board, rams into their big frontline, and now all your other minions can go around the frontline to hit face and finish the game.
Not great. 2 HP with no hidden/order/protected effect is going to get knocked off quickly. Then they nerfed him to only grow +1 strength each attack instead of 2. Bummer. I still picked up 1x. I've got the stars to spare and they rebalance cards.
The first 3 and must-buys if you have the stars. Don't forget to pick them up!
