Card rules & legalityOpen
Arvinox isn't a creature unless you control three or more permanents you don't own. At the beginning of your end step, exile the bottom card of each opponent's library face down. For as long as those cards remain exiled, you may look at them, you may cast permanent spells from among them, and you may spend mana as though it were mana of any color to cast those spells.

Sources, methodology, and disclosureOpen
NeoPrice and Pricing Confidence use the existing NeoCardAlpha methodology. CardTrader is the inventory source, TCGplayer is the primary pricing source, and Card Kingdom is validation-only.
NeoCardAlpha may earn a commission from certain marketplace links.
Card Kingdom retail validation is visible when a matching product is available, but it remains a validation source.
