So I have been away from magic since around the Alliance series and I see there have been A LOT of changes since then. I have been looking at cards online, doing research and such and I have a fun, simple deck idea that keeps coming into my mind. A mostly artifact deck with low/no casting costs. There are several artifact creatures with 0 casting cost: ornithopter, hornet, memnite, phyrexian walker and I am sure there are otheres. I have also seen cards, and I forget the name of it that each turn will add a +1/+1 counter to all artifact creatures. I think a guy could build a simple deck with lots of cheap/free creatures that get stronger each turn. Would this be practical?
