Planeswalkers are getting more and more attention in Standard. It's no surprise, as recently-introduced planeswalkers have been exceedingly powerful.
Finally, there is a counter to all the superfriends decks in the form of Sparkhunter Masticore, which is fully-protected from all planeswalker effects.
Teferi planeswalkers will no longer have a target for bouncing and Ugin will not be able to remove Sparkhunter Masticore.
Saprkhunter Masticore is also a colorless card, which means it can be in any deck.
