Cool idea. What would you sharpie in? "search for an artifact that costs 1 or less"? Something like that?
edit:But then tapping for 2 doesn't make much sense.... unless you fetch an X!
Commander cards always feel fake. EDH and commander are different in the same way Portal and Portal 2 are. The second one is designed with multiplayer in mind, but the levels feel really about finding the intended solution rather than exploration and experimentation.
Not a fan. I don't like vigilant things that eat anything attacking into it, but if 4 is too slow for Wrath of God in your cube, maybe this is not so offensive.
Hanna, Ship's Navigator looks cool. It makes me want to make an instant the same way I made an instant version of Captain Sisay:
I wonder if the rest of the crew do cool things too?
But seriously, you cool cats who run Pyromancer's Goggles, not only is it cool, but is it good? Is it worth spending an entire turn to cast? I'm definitely interested.
Edit: How do you think it would be at 4 mana?
My shallow and occasional thinking about UG is that I won't bother giving it a theme, since I already have a graveyard-shenanigans theme in UGB. I'm fine just running a few UG cards to support that.
