Ydwen Efreet

When this creature dies, destroy all creatures blocking or blocked by it. They can't be regenerated.

Attacking creatures get +2/+0 until end of turn.

Banding (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are blocking or being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.) As long as this creature is attacking, prevent all damage Deserts would deal to this creature and to creatures banded with this creature.

The next time a source of your choice would deal damage to you this turn, instead that source deals that much damage to you and Eye for an Eye deals that much damage to that source's controller.

As this enchantment enters, choose a color and an opponent. White creatures get +2/+1 as long as the chosen player controls a nontoken permanent of the chosen color. When the chosen player controls no nontoken permanents of the chosen color, sacrifice this enchantment.

T: Destroy target Djinn or Efreet.

Trample

Blocking creatures get +0/+3 until end of turn.
