Tayam, Luminous Enigma
Legendary Creature — Nightmare Beast
Each other creature you control enters with an additional vigilance counter on it.
, Remove three counters from among creatures you control: Mill three cards, then return a permanent card with mana value 3 or less from your graveyard to the battlefield.

You can remove any three counters to activate Tayam’s last ability, not just vigilance counters.

If a card in your graveyard has {X} in its mana cost, X is considered to be 0.
(wotc • 2020-04-17)
Because the activated ability doesn’t target the permanent card in your graveyard, you may choose one of the three cards you put there from your library.
