I once did a review for this card here.
Now that the format has changed one is force to ask them selfs a simple question. Where does Dekoichi stand in this format? With out Tsukuyomi and Chaos Sorcerer it's hard to see how this card will effect the metta.
I currently run it, but it's not the same. I find it's effect to be more critical then before. Now that plus one can be very hard to beat. Also with out Tsukuyomi, it is very hard to have massive advantage. From the looks of things UDE found a nice way to make that draw be worth it.
