I've run across a few during trades and they tended to stand out because I was aware that fakes existed.
In 2019, an anonymous buyer purchased an unsigned "Pristine 9.5 grade" Beckett Grading Services-graded Alpha Black Lotus for $166,100
Boom // Bust, a red MTG card that blows up lands on both sides of the board, has shot up more than five times its original value in under a week
There are 39 MTG cards with Channel these are the top 30 most-played
Apart from lands, ramp, draw, and removal, I would make the other categories "enablers" for cards like Awakening Zone and "payoffs" for cards like Dictate of Erebos You might notice you're not running too many ways to generate enough tokens and a tad too many sac outlets or payoffs that aren't triggering often enough
While I do have my hesitations with him, he seems like a decent fit for now
