The set features a new Teferi planeswalker, reprints of powerful cards, and the return of phasing—a mechanic not seen in Standard decks for over 20 years.

While the official stream revealed only a handful of cards, Teferi, Master of Time, stood out.

A 4 mana blue planeswalker, Teferi enters the battlefield with 3 loyalty counters and can activate his abilities at instant speed—as opposed to normal sorcery speed—essentially giving all his abilities Flash.

But imagine this card during a multiplayer battle: the card can activate abilities at any time and on anyone’s turn.

Returning in Core 2021 and featured on Teferi, Master of Time, is phasing.

The Core 2021 set has cards that are not Teferi, Master of Time.

Beyond featuring beautiful art and a reprint of a green ramp card that nicely fits my penchant for big, dumb creatures, the fact that this set is centered on a powerful Black mage speaks to me.
