Doubling Shenanegans (Modern)

Doubling season decks are not a new thing by any stretch of the word. But I figured I'd try one anyway.

I have a RG deck which uses Tooth and Nail to get Xenagos, God of the revels and Emrakul, the Aeons Torn out. 30/30 haste annihilator 6. It hurts if you get it out.

With the recent(ish) introduction of Samut, the Tested, you can get the same effect with doubling season + Samut. So you get her out, she ultimates instantly, you find your two creatures, boom. I wanted to find another card that does the same thing, and can ultimate instantly. That's where Jace comes in. He's filthy. I ult him, cast him again, ult, cast again, ult, then as a final, Samut, ult, death.

Oath lets me cast Samut if I need to, but she's really not in here to be cast with mana. she's in here to be hit with Jace.

Iona, Shield of Emeria is in here if I see the swing won't be enough to kill the opponent outright. if my opponent has more than 30 life, or if he has a way to chump emrakul, then I will put out either emrakul + iona, or Iona + xenagos.

I'm pretty bad with sideboards so I kind of just copy/pasted one from another similar deck.
