Starcast with Kroak could definitely have legs.
Tonight I'm going to try LCoD, Kroak, Incantor and Castellant.
Everblaze comet, spell portal, purple sun.
3x Libs and 4x Desolators that can either bunker up in the Staunch Defender bubble or use their speed to grab objectives or deepstrike and do further chip damage with the dracoths' bad breath.
Will report back.
