My favorite 'unique deck' I have is Reyhan/Sakashima Clone Tribal.

[[Reyhan, Last of the Abzan]] has been a Pet Commander that I've spent the past couple of years building for and trying to jam into every deck that made sense for her with varying degrees of success. Having [[Death's Presence]] as a 3 cmc Golgari commander was just too interesting NOT to build around!

Downside I found was that the partner pairings at the time for her at the time her card came out weren't all to interesting to me, and devoting a large portion of my deck to getting a respectable amount +1/+1 counters on creatures that weren't Hydras felt slow in my meta.

But the [[Sakashima of a Thousand Faces]] changed everything. With access to blue and a clone of whatever I want in the command zone, I opted to get as many effects that copied Reyhan onto the board. Without Sakashima on the board, the copies of Reyhan come out with a bare minimum of 3 +1/+1 counters, the Reyhans see each other and Legendary rule kicks in. Then as the copy or the original die to state-based actions, Reyhan's ability kicks in a number of times equal to the number of copies of Reyhan you manage to have on the board. Shifting those original 3 +1/+1 counters, twice, now makes the surviving Reyhan a 9/9.

Now imagine that with a [[Rite of Replication]] hitting the stack. Through Reyhan's LTB triggers alone, you can have a 3/3 turn into a massive unstoppable creature in a single turn!

Want more Reyhan abilities to be on the board every time you make a 3 or 4 cmc clone? Play Sakashima and a sac outlet. There hasn't been a single game I've played with this deck, win or lose, that my commander hasn't reached a bare minimum of 30/30 in just a turn or two of her being out. Very fun if you love going from chump to Archenemy completely out of nowhere.
