@fsecco Didn't really dedicate much thought to this card in particular, honestly. This particular mechanic (look at the top X cards of your deck and choose certain card types) comes up often so I just made a google sheet to help me and I thought I would share the numbers in this thread to help people with their evaluations. If you don't think it's worth exploring at those numbers, fair enough, but at least you have something concrete to go on.
If I was intrigued by this card, I would probably grouse about the laziness of just plugging it an existing shell without trying to build around it, but these effects just interact so poorly in a format with such a large percentage of Sphere effects. Probably a cool card in Modern though. Triggers Arclight Phoenix by itself and practically flips a Thing in the Ice. Or jam some Pyromancer's Ascensions and Baral's. Fun times.
