Back in the day, in v1, the endgame strategies were pretty interesting: I closely followed the discussions between One Mind and Elder Pact (Frenzied wrinklers and Eldeers respectively). With the addition of prestige upgrades and the dragon auras the comparison changes. I've read MasterSparky's thread regarding One Mind vs Pledge with regards to clicking speed, but not how this relates to Elder Pact.
From a personal point of view, I honestly always disliked the slow playstyle of One Mind and it seems so odd to Pledge, something that was basically not done back in v1. Also, in v2 it seems easier to sync cookies and deers due to increased spawn rates on GCs, so slightly removing the RNG component during Elder Pact. However, with the added chance of FDF I can understand One Mind and/or Pledge overtaking it.
So, tl;dr, how viable is Elder Pact statistically compared to One Mind or Elder Pledge in v2?
