So, I'm obviously on board with breaking singleton, as it seems most on here are. The question I'm thinking about now is when/why to break singleton. I originally built around the idea of doubling up on the "build-around" cards like Haakon, Vengevine, Spider Spawning, etc. The more I'm thinking about it the more I'm thinking the cards that should be breaking singleton are good support cards, especially multi-archetype support cards. Having two copies of Haakon or Burning Vengeance would make your deck more consistent and increases the chances the card shows up in pack one, but having two players trying to draft that archetype wouldn't necessarily work.
What do you think? Better to have two Vengevines and one Wild Mongrel, or one Vengevine and two Wild Mongrels (which supports anything that needs a discard outlet, like Madness, Haakon, Vengevine, Reanimate, Loam etc etc etc)?
