Vile brew Common

+2 recruits for every common Runic Barbarian or Soldier in hand

I like the idea :-) it is a very thematic, lovely and also a bit funny card...
nevertheless, it has no "restriction", so it may give you up to 14 recs without penalty (compared to Siege preparations: +7rec (net) or Avenger: rec+5). I know, it only works on common cards... but with already 4 you are overpowering the two stated cards.
Also the costs are quite low... maybe it shuold give you only 2 recs for runics, and 1 rec for soldier/barb. Would make it even more thematic imo ;-)

you are right, I redid it to give 2-9 recruits

this would be ridiously op card in barbarina and solider deck 1 recruit for each is more reasonable

it only gives for commons which are usually 3-4 in hand

Vile brew, common, 1b,1g

Recruits +(N+2)
N=#common Runic Barbarian or Soldier in hand

hmmm... now it's not that funny anymore... you have to calculate... it looks balanced ;-)
...you have even a minimal gain, if there are no "guests" there at all... I thought, it might give "runic" a little buff. Giving it a "2 recs for runic" would make some people consider to put some runic stuff in.

...another idea, to increase "diversity", could be as follows:
if common runic in hand>0: recs+4
if common barb in hand>0: recs+3
if common Soldier in hand>0: recs+2

up to recs +9... for three matching cards :-)
...no recs for nothing, thematic, as dwarfs ALWAYS love that brew, while soldiers shall not drink, when in duty.
