'Phyrexia' cards

When you planeswalk to Furnace Layer and at the beginning of your upkeep, select target player at random. That player discards a card. If that player discards a land card this way, they lose 3 life. Whenever chaos ensues, you may destroy target nonland permanent.

When you planeswalk away from Norn's Dominion, destroy each nonland permanent without a fate counter on it, then remove all fate counters from all permanents. Whenever chaos ensues, you may put a fate counter on target permanent.

When you planeswalk to Norn's Seedcore, chaos ensues. Whenever chaos ensues, reveal cards from the top of your planar deck until you reveal a plane card. Planeswalk to it, except don't planeswalk away from any plane. Put the rest of the revealed cards on the bottom of your planar deck in any order.

At the beginning of your upkeep, sacrifice a nonblack creature. Whenever chaos ensues, create a 2/2 black Zombie creature token.
