Primal Clay

As Primal Clay enters, it becomes your choice of a 3/3 artifact creature, a 2/2 artifact creature with flying, or a 1/6 Wall artifact creature with defender in addition to its other types. (A creature with defender can’t attack.)

Breezekeeper

Flying
Phasing (This phases in or out before you untap during each of your untap steps. While it’s phased out, it’s treated as though it doesn’t exist.)

Equipoise

At the beginning of your upkeep, for each land target player controls in excess of the number you control, choose a land that player controls, then the chosen permanents phase out. Repeat this process for artifacts and creatures. (While they’re phased out, they’re treated as though they don’t exist. They phase in before that player untaps during their next untap step.)

Cloud Elemental

Flying
Cloud Elemental can block only creatures with flying.

Benthic Djinn

Islandwalk (This creature can’t be blocked as long as defending player controls an Island.)
At the beginning of your upkeep, you lose 2 life.

Vaporous Djinn

Flying
At the beginning of your upkeep, Vaporous Djinn phases out unless you pay . (While it’s phased out, it’s treated as though it doesn’t exist. It phases in before you untap during your next untap step.)
