Two conditional switches sit on the same body, and each one asks something different of the deck around it. The 8/8 clause turns a graveyard count into a body upgrade: fill the yard to eight and a 4/5 becomes a genuine threat, which slots this into the self-mill and delve-adjacent shells that were already stocking the graveyard for other reasons. The hexproof clause runs on a separate axis entirely, keying off a board-state condition (another Villain under your control) rather than anything you do to your own library. That split is the interesting part. Most creatures that reward graveyard investment also want to protect themselves, and here the protection is deliberately decoupled from the payoff: you can hit the 8/8 without hexproof, or hold hexproof at a base 4/5, and only when both conditions align does the card become a hard-to-kill eight-power blocker-and-beater. The Villain-matters clause is the tell that this was built to anchor a tribal shell, not to stand alone; on an empty board next to no other Villain it is a plain body waiting on the graveyard math. The design leans on you to supply both halves, and the reward for doing so is a creature that is simultaneously large and safe from opposing removal, which is a real ask in blue, a color that historically buys evasion and protection rather than raw size.
