You have to keep in mind that there some clans that don't really need reinforcements but alternatives, 2 of those clans are
Bangers and
GHEIST, which already have more than decent cards.
for
Bangers both new cards offer the alternative of higher damage for less power than the existing cards, even if many players prefer more power over more damage that isn't the case for all, I played many decks with 6 power cards like
Xia Leming,
Windy Mor, kenny etc., the bluff factor is very important and can win games just as well as a "power" card
So they are meant to offer an alternative style of playing the clan, not necessarily being clearly better than the older ones... where would we arrive if each week we would make 4 cards that outclass the previous cards in their clans?
for
GHEIST:
Luba is a decent common card, good power and an ability that can be very useful, protected against stop ability by the bonus. in the worst case she will be something like 7/4 or 7/3 stop ability, which is decent, and in the best case she will be 7/6 - 7/7 stop ability at lvl 3 which is outstanding, so don't underestimate a card until playing it
Toro is a great lvl 4 card, easily comparable to
Ratanah if not a little better in many situations, his ability is protected by the bonus, and a 9/5 at lvl 4 is very decent, maybe more value for the number of stars than
Rolph.
Toro can also be easily compared to blaaster - one of the greatest cards of the game - and he can easily defeat blaaster
