Tyrant is really powerful, but Surturs strength will be constantly replenished by the Flame...
Furthermore, the closer to the Eternal Flame Surtur gets, the stronger he becomes...
In addition, the Casket proved capable of holding Odin; its not out of the question that the Casket could hold Tyrant as well...although I wouldnt be surprised if it didnt prove capable of holding him.
Odin and Tyrant are two wholly different beings though.
Tyrant, even "DP" Tyrant, operates on a universal scale. He's the closest thing you can get to being an abstract without actually being one. Somehow, when Galactus created him, he linked him to the biosphere of every planet in the universe. That's what he draws his power from. His connection is so absolute that he's aware when a planet is destroyed and it pains him.
His control over biospheric energy is so complete, he can even absorb it after it's been synthezied into other forms of energy like the Power Cosmic.
This isn't my opinion or speculation, it's all happened on panel.
My OPINION is that I think he would destroy Surtur with or without Twilight no matter how close he is to the Eternal Flame. The Casket is the big quesion mark because I don't know how Tyrant would react to it. IMHO, he could escape it or it would fail to trap him.

The issues stating that Tyrant is linked to biospheric energy, which I think you are grossly overplaying, were so horribly written that no writer has been able to pull Tyrant from that mess and make him a workable character. Tyrant is a complete write-off as a character.
And Surtur still stomps him.

Surtur wins,having twilight and casket of winters it's a slaughter. DP tyrant is powered by bio energy of planets he is not universal, that's over playing him. DP is couple notches above Thanos, I put DP Tyrant right below Odin if that, but still tyrant is not going to beat this version Surtur.
What's so horrible about that writing? He's a creation of Galactus and utilizes the same properties. He can be a workable character just like anybody else who has died in comics and made a return.
The fact is that it was mentioned multiple time by both Galactus and Tyrant. Galactus was in fear of his life and the Surfer through a rapport they shared mentioned it.
Galactus fed on a planet that he said made him feel more powerful than he had in ages AND fought Tyrant on Galactus' home turf. And he still lost.

How is he not universal if he draws power from the biosphere of every planet IN THE UNIVERSE? It's not like I'm making this up. It's right there on panel.

Are you kidding me? The fact that Morg regressed to being a ghetto thug with clever lines like, "Think again, butt-face" and calling Air-Walker a "nerd" should be sufficient.
