Yuriko "low cost" (EDH / Commander) [Revision 25]

The mana base is blue. At least focusing the first turn. It only has a first turn black drop.
The main idea, like any other Yuriko deck, is to be able to play it on turn 2. For the first hand I like to have a turn 1 drop and 2 mana (blue and black). As the deck is on a tight budget, we cannot be too demanding apart from this.
From here on, it's all about manipulating the top of the deck to do as much damage as possible.
Adventure creatures are very useful as they allow you to play them and at the same time they do good damage when revealed with Yuriko.
In midgame I use some tricks to be able to play ninjustsu while controlling the tables.
And finally, "Lim-Dûl's Vault" or "Insidious Dreams" allow you to order the deck to finish off your opponents at the right time with the highest cost spells.
Before I used sol ring and certainly in long games it can be very useful but I don't see it as essential either.

**As a next improvement I want to try scroll rack and sensei's divining top for more effective deck manipulation ($$$ increase).
