Trust me or not,it is true. Nightmare,Piranas,Roots and GHEIST doesnt have high chance against mono Skeelz.
La Junta,Fang Pi Clan,Jungo,Freaks 0%.
+2 power clans has better chance.(All stars included)
Attk manip (so:Junkz,Uppers,Sentinel,Montana,Rescue,Sakrohm is 30-40% chance)
Vortex and Pussycats has higher chance.
I talk about Skeelz in skiller handz.
Spiaghi can be exchanged with Lehane IMHO. (Maybe with C Wing )
