Yeah, I mean that's fair that you are basing your opinion on your experiences. That's all we can really do. I've just basically won every time I've been able to pick up Obosh, even if I picked him up Pack 2 Pick 1 and had to scramble for playables. Someone did an analysis on winrates in limited with the companions (I know I saw it on Reddit, but not sure if it was posted in here) and Obosh was, I think, second highest as a companion at about 70% IIRC.
EDIT: Sorry, I was wrong. Obosh has a 75% winrate as a companion lol:
Oh I love this chart! I had originally pegged Lutri as the best, with Jegantha behind, but I definitely had that backwards. Jegantha is so much lighter of a restriction and having a guaranteed 5-drop fatty (and thus getting to skimp on the dorky middle bit of your curve when drafting) really is better than just guaranteeing a curveout. I had originally unerestimated Lutri's restriction and overvalued the guaranteed curve out in a format where big plays are the norm.
The data I really want to see is the "first-pick-adjusted" rares. When you first pick a companion, how likely are you to meet it's restriction, how likely to play it at all, and what are the win rates for each.
Also I love that the numbers for Zirda basically just say "if you got the nuts cycling deck you're basically guaranteed to win."
