Sultai ramp or sultai “big midrange”.
A lot of value in the lands, they add a lot of utility to the deck and help in the late game.
Coiling Oracle- body that cantrips/ramps while providing A blocker
Scavenging ooze- we run a pretty large removal suite, this helps gain life lost early on and eats pieces from the yard vs snapcaster, dredge, and Phoenix strategy.
Courser of kruphix- we put a lot of lands into play, life buffer is nice, let’s you get lands off the top to draw into something better the following turn
Tireless tracker- obviously nice with lands and is one of two ways we can get card draw
Hydroid krasis- late game mana sink, gets us uncounterable card draw vs control, small life buffer vs burn
Primeval Titan- used as a value engine instead of a combo piece, lots of utility lands, tutor up what ever we need.
Field of the dead- is usually a GG after a primeval titan, just get fetch lands to get extra triggers.
primal command- a life buffer while we wait an extra turn to play our threat we tutor'd up.
SIDEBOARD
Pulse of murasa- burn, Phoenix (you can put the Phoenix back in their hand) control
Unmoored ego- combo is our worst matchup, names a tron land, valakut or lightning storm/ad nauseam
negate- combo and control, pretty explanatory.
damnation- current slot for trying to deal with "stompy" decks (humans, fish, spirits)
engineered explosives- general catch all, also for stompy decks
leyline of the void- graveyard decks are here to stay
thrun- used for rock decks and control. could also be a carnage tyrant, I like thrun for the regenerate
thought going forward
I think I could maybe add an engineered explosives to the main to help with stompy decks. Could also play a scapeshift in place of primal command as an extra wincon to win with field of the dead but it does require me to have 7 lands.
