Once a creature that has reach because of Sphere Grid's last ability has blocked a creature, removing all +1/+1 counters from that creature or causing Sphere Grid to leave the battlefield won't cause that creature to stop blocking
Let me know on Twitter, Id love to hear your thoughts on it
I can definitely understand people not putting Yawgmoth, Thran Physician in their top five list as its only played in one deck, which isnt a dominant player in the metagame either, but the card makes the archetype and there arent too many good mono-black creatures in Modern right now
We don't have a single card that costs more than two mana, so we can get by with playing only 19 lands, with the idea being that we'll flood the board with cheap but powerful Humans, pump them up with cards like Thalia's Lieutenant and Honor of the Pure, and hopefully close out the game before our opponent gets a chance to recover with their more powerful (and likely more expensive) cards
While this selection falls slightly short in value compared to some previous lists, two cards hit the mark
