I've been testing a few copies in my Jodah, the Unifier deck. I have Reclusive Taxidermist, Katilda, Dawnhart Prime, and Relic of Legends in there, as it is. Tyvar, Jubilant Brawler could make it that little bit more snowball-y that it needs. One of the problems I consistently find with the deck is that drawing multiple copies of Katilda or Relic kill the tempo of the deck, entirely. This can also trigger Jodah to find legendary creatures and be hit on a Jodah trigger if I cast a 4mv+ legendary spell. I took out a Katilda and a relic for testing, leaving me at 3 Katilda, 2 Relic, and 2 Tyvar. In the twenty or so games I've played with the changes, it's been noticeably less problematic. I'd really have to run another 50+ games to really see if its helping as much as I feel it is and not just experiencing a Good Luck sandwich with a dash of Spicy Bias; but it feels better, so far. I'm hopeful, at least. It's nice that it can also return any 2-drop legend I might want back out of the yard.
