He REALLY wants you to focus on his enemy upgrades, which consequently drains your hand when you do (-1 for 0 cost, -2 for 1 cost), and EVEN MORE to Optic Blast. Which leaves you 2-3 cards to other stuff like play events or actually field precious allies. Of course, FIELD COMMANDER and RUBY QUARTZ VISOR are built to counter this, but (1) you may or may not draw them, (2) they take up precious rounds to build out if found mid-game and in solo, and (3) Field Commander doesn't stick with Villains.
In short... multiple resource generator options seem to be necessary when building him.
