This was my first EDH deck, I changed the manabase over time and some of the utility cards, but mostly the core slivers have remained the same. The deck can win out of nowhere with Sliver Queen / Mana Echoes, but generally you'll just win by swarming the table with overwhelming forces (so to speak).
