Shard of Patience probably breaks this card slightly more than you'd like to anticipate.
It can be argued that we're making a 5 | 1 for 3 | 2 that's very easy to control. Not too bad, all things considered, but definitely something worth being cautious about... Especially since you can SoPa them all to oblivion.
SoPa will indeed be a trick to balance. For those interested, they can check out various threads on Alpha Wolf variants in openEtG (alpha wolf spawns 3 wolves, a 2|2 alpha and two 2|1 pack wolves).
Its quite effective, but not brokenly so... I'm not sure how this variant will play out though, nor if that will hold under current EtG meta which has less CC options than openEtG right now.
Glad you like the art. Wasn't sure what to do with it when the card I made it for a few use ago ended up a bust.
