What's that? Everyone else is making tiny leaders decks, but I still love making PDH decks, so here we are. I haven't made mono-blue yet, so here's Viral Drake, the coolest infect commander, with all the coolest targets for proliferate.
It looks solid and I'm used to 1v1 pdh, but do you have enough artifact creatures to get use of modular? Also, is the cycling from mage's guile worth it over Mizzium Skin or Veil of Secrecy? For fat stuff, Floodchaser and Opaline Bracers might work but they are kinda slow. If you want to abuse your commander a lot, more ramp is probably useful. Have you considered Sisay's Ring/Ur-Golem's Eye?
I wanted to build this deck a while ago but already have 2 mono-U decks. Let me know how it plays for you
I don't have a ton of artifact dudes (I think 6, plus transmogrant makes viral drake an artifact for maximum pwnage), mostly I just think a 1/1 for 1 that grows when I proliferate is pretty decent. Personally I really like the option to cycle mage's guile for so cheap, but I haven't actually tried it yet. I considered floodchaser and opaline bracers but I do think they're too slow. If bracers cost 3 i'd definitely do it, but sadly they conflict with viral drake so I think they're doomed. Ramp-wise I stuck to 2-drop ramp to guarantee a T3 viral drake, I'm not sure if expensive ramp is worth the cost. I can't reasonably play it until turn 5 without missing proliferate activations, so that's kind of clunky. Depends how the deck plays, if I think I need more early ramp or late ramp.
Unfortunately I haven't been able to talk anyone nearby to playing the format, so my PDH decks are mostly sitting around doing nothing. It's very sad. Hopefully I'll get to try it out at some point though.
