We tested Bard casting Tempered Fate, but didn't like how he fit into the Trait structure (and his spell needed work).
Second time we tried out Bard with his R as well - he was a champ in the original prototype set we build before set 1 for a while. That set had similar traits to set 1, though meaningfully different content (e.g. Illaoi as a low cost Pirate Brawler).
