My first attempt to build around
Righteous Intent. I think this card has potential. Using lifesteal units and relic weapons seems like a good route to take to capitalize on it. They paladin synergy helps power out Brel, and it fits the theme too.
Update: The paladin tribal theme was pulling the deck in too many directions. It helps to play a more traditional control role until the relic weapons and buffs to them can take over.
The metagame has evolved a lot since the early days when armory was good and units are much stronger now. However, the new tools to help buffs relic weapons might be enough to bring armory back.
