This deck's only real problem is that it doesn't have good answers to a couple of the stronger starter decks
Turn it face up any time for its mana cost if it's a creature card.) If Curator Beastie enters under your control at the same time as one or more colorless creatures, those colorless creatures won't enter with additional +1/+1 counters
Sacrifice after III.) I Exile target creature an opponent controls with power 3 or greater
You can find all of the cards in golden age, art deco, skyscraper, Phyrexian, and borderless treatments in Set, Draft, and Collector Boosters, in both traditional foil and non-foil
It's also an iconic card from Magic's history, which adds another layer as to why it's such a valuable card
If any of them turn out to be strong in Commander or Constructed, the nonfoils could end up being pricier than expected
