Really excited for
Chainer, Nightmare Adept - I love Reanimator (although he does not cheat on mana cost, sadly).
As for my less broken stuff, I want to build
Pramikon, Sky Rampart and
Marisi, Breaker of the Coil. Those two are pretty much the defensive and offensive spikes on the spectrum of political (pillowfort) decks to complement
Queen Marchesa (long may she reign). If that goes on, I may have to merge the decks into some 5c
abomination. The thought of buying the manabase hurts.
Greven, Predator Captain sounds like a really good way to get some very aggressive gameplay without resorting to the 'death by a thousand stings' types of strategies that Rakdos Aggro sometimes has. Even without a proper Voltron suite. Might be lacking without acceleration though, as Greven is 5cmc and does not have haste.
Anje Falkenrath enables Madness without a doubt, but Madness doesn't enable itself by lacking a wider variety of (good) cards in BR. Might be bonkers in a Reanimator/Vampire Tribal style deck with
Falkenrath Gorger as the key piece. I have my doubts though.
The Sultai deck has me the least excited. Nothing that really complements my love for graveyard strategies - but good for the color combination to finally see some variance. The Jeskai deck has pretty decent, but slow commanders. Not my cup of tea, but someday I might try it. As for
Gerrard, I absolutely want to break it so hard that someone flips the table - also: Boros Reanimator anyone? (With some loops and hoops).
The rest of the Naya deck doesn't really hit me good.
Atla Palani, Nest Tender is bonkers good, but I don't really know if I like semi-random fatties.
Most new non-commander cards are nice.
Dockside Extortionist will be
the card to have in RXx.
