I love [Oil-Gorger Troll]. ONE was one of my favorite draft environments, and I really loved the oil counter mechanic. I keep a very jank oil based edh deck around. He won me a bunch of games in draft, I love the art, and the "flavor" text (get it?) cracks me up.
What card sparks joy for you and why?
Avenging Angel seemed so cool when I first started playing. It didn't die, and a 3/3 flyer was pretty good a closing games (though not as quick as a Thorn Elemental).
I just loved how it kept coming back to avenge itself.
