Balance changes went live not too long ago and many are questioning it.
The main focus of the balances was to buff epics and legendaries but most are not noticeable.
Stan of Many Moons (SoMM) got the biggest bump and many are saying that it's simply too much. Why is that?
A fully powered up level 2SoMM's charged move now deals 280+ damage to all enemy units on the field. For 4 energy, this is essentially an arrow storm on crack as it can now wipe out most units just like that.
It appears that he is in most decks now and wreaking havoc. An easier counter is to make sure you have lightening bolt or mind control(big surprise for your opponent when their own unit wipes out the board for you!)
