Mine is definitely my Teysa Aristocrats deck.
https://deckstats.net/decks/113264/1206082-church-of-value-teysa-orzhov-sOrzhov was my first love when I started playing magic, and I knew building an orzhov aristocrats deck would be hard, since they get almost no ramp and no draw.
However I love the flavor of the orzhov guild, I love Teysa as a character and I love aristocrats as a strategy. I could totally make this deck competitive by going "full combo" with it, but that's not what I wanted out of this deck.
For my "competitive" deck I already have Lazav, so this time around I wanted a tuned deck, but not a deck that would feel unfair to my playgroup, and that's what I got.
I made this deck as optimal as I could while sticking to my strategy and theme, I added a lot of draw engines and ramp and mana rocks to hopefully make the deck faster than some other orzhov decks, however since orzhov doesn't really have access to counterspells, it is still possible for other players to answer my threats with removal.
Since aristocrats need a lot of elements to get going (sac fodder, sac outlets and payoffs) the deck isn't as consistent as my Lazav deck, but I love all the crazy interactions, synergies and value engines I can get going on when things line up.
The deck has a lot of my pet cards (
smothering tithe,
reassembling skeleton) , cards I had always wanted to play (
Bitterblossom,
Ophiomancer) and all in all is just a joy to pilot. It's a deck I'm always down to play, and this deck feels like my baby, I'm very proud of it.
(I'm also proud of my Lazav deck but just pulling out this deck with my playgroup usually makes me archenemy lol, and while I enjoy seeing all the other players spending all their ressources to stop me, sometimes I want to actually be able to play my deck and Teysa allows me to do that).
