'Kaldheim' cards

When you planeswalk to Littjara and at the beginning of your upkeep, create a 2/2 blue Shapeshifter creature token with changeling. (It is every creature type.) Whenever chaos ensues, choose a creature type. Put a +1/+1 counter on each creature you control of that type.

Players play with the top card of their libraries revealed. Spells that share a card type with the top card of a library can't be cast. Whenever chaos ensues, target player loses life equal to the number of cards in their hand.
