Mana Burn

[Durahan]

How does it work if two players both have floating mana and you reach the end of the phase? Does the active player take the mana burn first, or does it happen simultaneously?

I guess my question really is if you have two players with floating mana, can one player wait for the other to burn first before using their mana on an instant.

Mana burn occurs after both players pass priority on an empty stack without performing any game actions in the last step of a phase. Both players mana burn simultaneously, and neither player may play spells or effects until the next phase begins.
