Protocol seems more White than Red, really... sharing abilities across the board is more of a white thing, community and so on, tribal lords not withstanding. Are all of the creatures of the block artifacts? If so, Machinate seems slightly redundant, and would probably be suited to simply being on an individual card (that places machinery/wire counters on things, perhaps?) - unless, of course, you're trying to manipulate your opponent's creatures, in which case it seems fine (very blue... manipulative), though I think the mana cost for the process of Machination could be lowered to 2 (so you aren't too mana-stretched early game).
Drain seems a bit underpowered, but my opinion of it could change when I see the cards involved. It seems pretty black, though, and it should be pretty fine if the Drain cards are powerful enough / there is incentive for sacrificing so many creatures at once.
