It is so strong that when I try the Selesnya version of the deck I have started to add it as my only Blue card (which is also part of why I have shifted my focus back to Simic)
Heroes are a fairly scant archetype, but that just makes the deck easier to upgrade since you only really need to buy packs of Spider-Man and Marvel Super Heroes
Any time The Infamous Cruelclaw deals combat damage to a player, you get to exile the top cards of your library until you find a nonland card
Hunted Troll, for example, gives someone enough 1/1 Faeries to trade in combat, but regenerate means you win in the exchange
Perhaps you can represent the tokens with fresh-baked cookies and hope the smell affects their judgment
All in all not bad, and while this one has already jumped a bit in price since the $0.50 it was sitting at for three or so years, I think it has room to grow (especially if were leaning more and more into casting spells from exile) from its current $5.50 price point
