We are only three weeks into the season for Throne of Eldraine
Callous Oppressor While you wont necessarily run into this in every deck, Callous Oppressor has a lot of potential homes
After the first turn, Search for Tomorrow is generally worse than other options, which makes drawing multiple bad and makes drawing it in hands that need to use Arcums Astrolabe for green bad, so Ive gone down to one, since it is the best first-turn play if you have it, and Im also playing one Sakura-Tribe Elder, one Cultivate, and one Kodamas Reach
Since Valley Floodcaller can come down at instant speed, there is a chance that players experiment with this, but losing your enabler to the Ultima might make this a bit too resource-intensive for control decks
With turnaround times at major grading services ranging anywhere from a few days to over a year, I didnt want to absorb the risk of buying cards, sending them off to get graded, and then have to watch helplessly as the price point/support that I bought the raw card at get decimated as card values were to fall (and I didnt have my card back from the grading service yet)
