Salt Mining (Historic) [Revision 20]

Fun for groups

play as many Soul Warden, Soul's Attendant, Auriok Champion, as possible. Deathgreeter and Authority of the Consuls are fine choices but don't trigger on your own creatures entering the field, they only act as extra triggers for Epicure and Cliffhaven

Put out Panharmonicon if possible.

Play Crested Sunmare or Regal Bloodlord. One single creature played on any turn is enough to trigger Crested Sunmare and Regal Bloodlord's token creation at the end step due to soul warden and co. So every time an opponent creates a creature you'll create a token at their end step which will trigger more instances of life gain per creature.

Drop Epicure of Blood or Cliffhaven Vampire. The more people you play with the more hp you gain. The more Soul Wardens or Ciffhavens out, the more damage you'll do. For example:
5 Soul Wardens/Attendants/Champions + 1 Panharmonicon + 1 Cliffhaven/Epicure = 10 damage to each person when they play a creature or a creature simply enters the field, then at each of their end steps you'll create a token, triggering them all again doing a total of 20 damage to each person because someone played a creature. This would also heal you 20 life per opponent.
Cliffhavens or epicures stack so adding more only gets worse. This gets even worse when your tokens enter the field due to your own healing, triggering more lifeless for opponents. Effectively fueling itself each opponent's turn.

Follow up with Secure the Wastes for another bomb. Or use it for life gain if needed, but try to save for a bomb.

Use Thrull to get retrieve panharmonicon, as well as Epicure and Cliffhaven (they have a higher priority than other creatures) for when they're inevitibly sent to the graveyard. Use Emeria for creatures late game and to bring back Thrull
