The card was errata'd in 2017 (a massive 15 years after the card was first printed) with the introduction of Link Monsters to the game, but prior to then, the effect of Darkness Approaches was to flip a monster face-down without changing its battle position

You can only use this effect of "Odd-Eyes Advance Dragon" once per turn

To top things off, Teferi's -10 ability gives you an emblem that allows you to activate Planeswalker abilities at instant speed even during your opponents' turns

Not that it wasnt available, mind you
