Worldfire

Works, assuming you can cast {Worldfire} as an instant.

True! Forgot it was a sorcery! 😣

That's what Gorzo was working on here:

My combo right now for world fire would be to oblivion ring a creature of mine that has haste hopefully and Worldfire before combat. Creature comes back and I swing for the win.

R/G mana ramp, splash white. Not impossible in standard. I was thinking more for EDH though when getting 9 mana is no problem, and taking out all your opponents at the same time is epic.

[Ghebert]

Yea. I only standard. My card pool isn't outside of standard at the moment so I have a big disadvantage there.

[BlackJester]

O-Ring, {Fiend Hunter} or even {Leonin Relic-warder} on your own artifact creature would be good.

If you don't want to splash white, {Helvault} is another option...

e: scratch that. worldfire would exile the Helvault, meaning it doesn't go to grave and crack open.

{Worldfire} and {Misthollow Griffin}

{Worldfire} and {Misthollow Griffin}

you still need the four lands/mana to cast it. By then they could have top decked a mountain and a burn spell
