Yeah. The latest league dump (https://www.mtggoldfish.com/tournament/competitive-standard-league-2018-05-21#paper) has some very interesting Sultai and Esper decks.Quote from CrankyOM »I’ve been trying to figure out a way to make Esper work as I really want to smash Lyra and Shalai into a deck with TSG and Lilly. Gonna go through a league or two today and see if I can put it all together.
I've actually brewed 4 color (no red) on the theory that Urza's Ruinous Blast could be good. Fortunately, I have been saved from playing it by using a shared collection with limited Scattered Groves. On the unlikely event that the mana works, it will probably run into the fact that the best cards in standard don't get hit by the Blast.
Edit: SaffronOlive goes deep on Muldrotha. Benefaction of Rhonas! The non-budget version is interesting to me, although I tend to think of Muldrotha as a value card more than a buildaround. The synergies between Muldrotha and Walking Ballista are intriguing.
