I find this release a little concerning, to be honest. Not the cards themselves: going by the current rules, all except
Kalder are some sort of useful. But with the announcement of standard about a week ago, it raises questions about whether the UR staff is really dedicated to the issue of balance in UR:
Berzerk, a clan which will have all twenty something of its cards make it to standard mode, gets another release.
All Stars receives another 5 star, of which they already have 2 making it to standard and possibly only one 3* that will make the cut.
Kalder will be one of likely 3 2*s to make the cut for
Piranas, and has a very shaky ability in a clan which doesn't back up the ability with its bonus.
Varoslav seems the only sensible release with Standard in mind, and even he will serve as the 4th 3* available, though I'd personally take him over
Bikini Joe Ld or
Karmov.
I might be overlooking some important facts and I'm just worrying for nothing, but this release did not help the case that standard will have good clan balance.
