I have to build a deck that will compete with multiple decks and I am looking for your input. The tournament is single elimination, Vintage Rules. Here are the decks I assume I'll face based on the players I know.
B/G infect
RUG Slivers
B/R Land Destruction
B/U Mill
Mono Red Goblins
I am leaning towards Mono Blue/Artifacts, control focused. Early drops will be counters and blockers with big finishers. There is no side board since it's single elimination. I'm open to your suggestions?
