While I personally think that Exocrine s ability to clear the board and possibly even finish off opponents if life totals are low enough pushes it over the top, there are a variety of useful effects to be found among these creatures
Sharding Sphinx, on the other hand, creates a situation in which your army gets larger and larger while providing more fodder for sacrificing (for the aforementioned fun and profit)
Maybe its particularly good as a colorless go-wide theme (note, you also get to manifest, giving yourself two 5/4s and drawing to replace them), but I just think that the rest of the titans are much more impactful
Other than that, it follows the standard templating that appears on most instances of this effect
This card is so powerful, that if it were to be knocked out, your opponent would take three prize cards
Thematically, nearly every card in Kaldheim is an absolute banger - the kind of thing you could happily sing a song about while drinking mead and doing your taxes
