Angry Grimace
Two cannibals are eating a clown. One turns to the other and says "does something taste funny to you?"
I wouldn't get Kiora immediately for $20. I think she's incredibly overrated. In creature-heavy decks, you'd rather have CoCo. In ramp decks, the impulse is going to wiff xx% of the time. Rather have Sarkhan Unbroken 9 out of 10 times.
I picked her up at $15. I think Kiora and Ob Nixilis are locks to trend downwards towards $10 in my opinion, but its not that huge of a loss and I love brewing with Planeswalkers. The biggest problem with Kiora is that whatever deck is using her pretty much also wants Jace to get value out of the yard, and a playset of Jaces is $170.
The lack of Satyr Wayfinder-like cards really hurts Sultai/Delve fueled decks a lot. The only way you're really fueling Delve is Jace and Kiora's minus, which is not exactly fast.
The Theros gods, much like Theros itself, were completely worthless.
Theros seems better than Battle for Zendikar, tbh
