The last three reprints continue to deliver, too
All you need is a way to buff him up and land a hit, and you're off to the races with an instant army that replenishes itself with each attack, or even grows exponentially True, Shroofus will mostly see play in the 99 of other, multicolored decks, but he can make for a powerful commander all by himself
This will also turn your dorks into an Ancient Greenwarden and play lands from your graveyard, Carnage Tyrant to make it a beater, Grunn, the Lonely King to double its power when it swings alone, Kamahl, Fist of Krosa to Overrun and make lands dorks, Multani, Maro-Sorcerer to grow massively in size and get shroud, Nemata, Grove Guardian to make a bunch of tokens, Primordial Sage and Soul of the Harvest to draw cards, Rampaging Baloths to landfall and game win, and that's just one casting cost
Plus, you get to play with the cards before anybody else
