Hey, I'm normally a Convergence player but I kinda fell bass-ackwards into owning Caine's Hellslingers and a bunch of chargers and cyclones. I was wondering, if I was going to take Cygnar to a tournament, what other caster should I take with him? I'm inclined to get Nemo3 for maximum electricity but before I do that I'd like to hear from those wiser than me.
Caine3 is ruined by infantry spam or things that deny shooting. Nemo3 will typically not cover those matches that well. In fact Nemo3 and Kara possibly do Caine3 better than Caine3. Gravediggers + Haley3 probably works better as the second list.
Gravediggers in general does seem to cover his Infantry weakness, Haley3 is a strong caster in GDs but there's other options too, like Siege2, and even some more out there casters as Jakes2, Caine2, Caine1, Haley1... All interesting options (though Siege2 and Haley3 are the most competitive I suspect).
Alternatively you could try some e-leap madness, running Storm Division with Stormlances and Storm Striders for maximum e-leaps. Siege2, Haley3, Maddox, Stryker2, and Nemo3 are all solid in Storm Div. You can go a bit wackier with Constance Blaize, Jakes2, Stryker3 if you like, but it doesn't usually make for the most competitive list building.
Getting really out there, Sons of the Tempest with Haley1, Caine1, or Siege1, are all interesting options, again not necessarily competitive ones, but you might have some fun with them!
