A fun mastery/armory hybrid I've been tinkering with in ranked.
There's not a huge selection of good relic weapons in Expedition, or removal to play the traditional control game. The units here do a decent job of keeping enemies at bay - especially the two mastery units, which pay off really well with relic weapons (note that Tota Colony also buffs weapons).
Ceremonial Mask, while a bit overpriced for its stats, can either instantly pop a mastery, or gain absurd armor with Kevasa. With Dragon Forge and Rakano Artisan it's often a 5-cost 5/5 anyway.
