A leak of Kaldhiem packaging confirms that Kaya will be one of the set's planeswalkers.
The new MDFCs are not just land/creature,spell,etc
Glimpse of Glory
(Sorcery, Blue):
Scry X, where X is the number of Legendary Permanents you control.
//Patch of Sacrifice
(Legendary Artifact, Colorless/2?): A legendary artifact (equipment).
When it enters the battlefield, choose an opponent. They play with their hand revealed for as long as this artifact remains on the battlefield. Equip (2 colorless): Equipped creature gets +1/+1 and “Tap: Scry 1.”
Plus a very good chance that snow-covered lands will be returning.
Skatharvosk, Root-gnawer
(Legendary Creature – Elder Squirrel, 1BGR):
Sacrifice a Forest: Untap Skatharvosk. It gains indestructible until end of turn. IF that Forest was a snow-covered permanent, Skatharvosk and each snow-creature you control gets +2/+2 until the end of turn.
3/3 Creature.
Kaya is currently one of the only planeswalkers without a card in the standard rotation, but of course the planeswalker who is BANNED in standard gets a new card as well.
Oko, Winter’s Liege
(Legendary Planeswalker – Oko, 3GU):
4 Baseline Loyalty.
+1: Create a 3/3 Green Elk snow creature token.
-2: Scry X, where X is the number of snow permanents you control. Draw a card.
-7: Gain control of up to X target nonland permanents, where X is the number of snow permanents you control. Each of those permanents that are creatures gain haste.
If these potential spoilers are real, well then I'm scared. Any thought? Do not blame me if these end up being fake, but the Kaya leak is real.
