Seems like a good and fun deck. Competitive but not so combo-ridden that it is no fun to play against. +1. As for your maybeboard, I think Path to Exile is better than Dispatch. Yes you will probably always have the metalcraft, but in the case that someone kills off enough of your artifacts and a threat is put onto the battlefield that needs to be dealt with, Dispatch won't get you there. Giving up a basic isn't too bad of a price to pay for slightly better consistency. I would put the Temple of Enlightenment in for one of the fastlands or a basic. The chance of you finding a fastland that early isn't phenomenal and otherwise it will come in tapped, but the scry is always useful.

I really like it. Lots of good synergy. +1 from me

evncrbch I agree with everything you said, I'll probably add the other temple too instead of the other fastland as well, thanks a lot!

And thanks TyrantofJund
