Rosa is good, 1 less power, but 1 more Damage + poison is good.
if you hit with Rosa, in the first 2 rounds, you can potentially 2 hit KO with a 4 or 5 damage card without using fury.
or a 2 or 3 damage card with fury.
Rosa opens a lot of doors.
while Edd, stop bonus, which is really important... only has 5 damage.
if you use em both together, you can use Edd for the second hit.
also, Uppers and Rescue have both been hurt recently, but Pussycats have come back in, so less attack bonuses, but potentially more damage reduction bonuses....
