Use a bleed immune champion then
The way I see it is to bring a poison immune champion (for the poison node), don't worry about the bleed because it deals 0 damage
Ghost+Hood kills opponents there quickly. There's also Omega Red, though you may need some boosts to deal with Void. If the previous node is filled, could bring a duped CMM to kill the opponent while her invulnerability is up, by ending the previous fight with 25 charges.
Could you use ronin? When you get debuff from void you could remove it.
Elsa Bloodstone?
Not sure why this is so difficult. Bleed immune champ means the bleed debuff never gets placed so it can't get removed. I take that node regularly with LC and have used Vison and Ultron in the past with no issue as well.
You just need a champ that minimizes, or takes no damage, from bleed.Corvus, Omega, and Old Man Logan come to mind off the top of my head. There may be others too, but those would be solid options.
Man I never thought about how cheesy it is to put Void in this now
