Dies to Removal

I kinda wish flash wasn't banned just so I could build a deck with it and worldspine wurm. Then I remember hulk flash and I chastise myself for ever wishing that.

So I'm playing a commander game waiting for a draft to start. My nekusar v heliod v brimaz v ????(naya tokens). My only non-land permanent is an astral cornucopia with one counter. The heliod player has heliod (not a creature), witchbane orb, and a magus of the disk (untapped with a mana open). The brimaz player has some white enchantment that forces everyone else to sacrifice a creature when one of his dies and a mentor of the meek. The token deck has a bunch of 1/1s and then he drops craterhoof behemoth and turns everything sideways at me. I have 6 mana open and tribute to hunger and counterflux in my hand. I point the tribute at the brimaz player, killing his mentor causing the enchantment to trigger, and the heliod player
activates magus of the disk, causing the naya player to cast boros charm to protect his horde which meets my counterflux. Unfortunately right after that rube goldberg wrath they start announcing seating so we didn't get to play it out beyond that.
