Wrasters most definitely are not broken. They are of limited use, but what you use them for (marker removal & condition removal) they excel at!
Malifaux Child, also in Infamous, is gloriously to drop more Pianos. How is 8 Pianos a turn not amazing?! Also, my friend uses the Child in Amalgam to copy Draw Essence for free when Hidden Martyrs is in the pool. Malifaux Child is solidly mid... nothing is broken on that kid at all.
I only use Barbaros as a Leader to play some messed up Outcast Nephilim crews, and for that alone as a three action Bring It "lure" into that heavy melee crew, he is so good!
