CS is getting all the attention, but lots of folks are stuck with CT, for the foreseeable future, so here's something I haven't seen mentioned. As unlikely as this is to occur, it's pretty sweet.
Midscreen
CH 6B, 6C, 2D, 6C, 66, 5C, j.C, j.C, 214D, 6C, 623A/B/C
Does about 4500 damage, uses 25% heat, but can be done without any initial heat. 6B's kinda cheesy in CT, but the speed buff in CS might make it better.
