Fair trade off for Freaks, Roots and GHEIST. GHEIST gets a staple 2* in exchange for susceptibility to damage, Roots get a slightly better stat-wise card but less efficient blocking of nukes, and Freaks although have Olga, lose Grudj, so pilling for them will still have to be controlled well.
Freaks benefit from getting Olga back even though at the cost of Grudj . Personally, I would take Olga any day.
Only thing I'm suprised about is Blaaster Cr . Great card, but I honestly suprised he got chosen over Beeboy for a perma-ban. Beeboy usually tends to get in the top 3 for most amount of weekly ban votes.
