Arch of the Lost Empire

Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.)
At the beginning of your upkeep, if you have the city's blessing, have no cards in hand and control no other permanents, you win the game.
Lore has it that it was the greatest city this land ever saw. Today, even the name have washed away on the shores of time and all that is left is a milestone for passing merchants.
