Teferi, Master of Time

Description

Teferi, Master of Time (PM21-75p, Legendary Planeswalker) is a blue planeswalker promo from Core Set 2021. He can use loyalty abilities any time you could cast an instant, including a +1 that draws then discards, a −3 that phases out an opponent's creature, and a −10 that grants two extra turns. In decks he serves as a control tool by enabling card filtering, temporary removal via phasing, and a long-game extra-turn win condition.
