Sutai Mega-Morph, taking a slightly differnt approach to mega-morph decks, running 4 of Stratus Dancer, in place of Den Protector. The dancer is more aggressive as a turn 2 drop, and it can block fliers, also the decks not playn a ton of low cost spells, so there isn't a ton of value for the protector imo. Additionally, everything that goes into the graveyard, except Deathmist Raptor, is fodder for Murderous Cut and Tasigur, the Golden Fang, so without den pro you can gogogo. Finally, un-morphing Stratus Dancer is a huge middle finger to any kill spells your opponent might have and allows you to keep on attacking, rather then just getting card advantage with den pro, but losing board state, And having mana up with a face down dancer and a Silumgar's Command in hand is a very strong way to lock down the board and get ahead with cards like Sidisi, Brood Tyrant, Deathmist Raptor, Ob Nixilis Reignited.

over den pro and icefeather aven because its a real aggresive attacker that can do some good stuff swinging in to Hangarback Walker then unmorphing and destroying the walker in response to their counter.
-Easily pump out 6/6

s and Sidisi, Brood Tyrants as early as turn 3 using Rattleclaw Mystic.
The Final piece to point out is the usage of Sagu Mauler. This guy is a beast! he has won so many games testin this deck. He triggers Deathmist Raptor and trades with or beats pretty much every creature in standard, and the ones he can't, can be hit with your kill spells. hes so strong he can race a Dragonlord Ojutai, even if they land hits and get cards, they OFTEN cant find an answer for him, and he beats the crap out of planeswalkers, as does Silumgar's Command.
+1 if you like it, and try it out it's a house.
