A new Teferi for a new standard!
This one is not as overpowered as the last few iterations of this planeswalker. But it is still a solid choice for any White-Blue Control deck.
It can potentially untap two of your lands, if you're using artifact lands, or it could tap those on the opponent's side. In either case, this is a really solid plus one ability that many players will find extremely useful each turn.
The minus two ability is good and the ultimate is simply fantastic, as it should be.
