Very nice pickups on those legendary cards! I'm one away from a maxed out Kulu Mastermind. I put all my glint into legendary this time and got a few to level 3 so it was worth it. Maxing them out is a serious challenge...
Great buys there, Kraken and Spirit Miner are so helpful, I love those cards. I'm not sure when the change over to new rewards are coming, so for now I'll be working on my legendary cards!
