Breathkeeper Seraph

Flying, soulbond (You may pair this creature with another unpaired creature when either enters. They remain paired for as long as you control both of them.)
As long as Breathkeeper Seraph is paired with another creature, each of those creatures has "When this creature dies, you may return it to the battlefield under its owner's control at the beginning of your next upkeep."

Fliegend, Seelengebunden
Solange der Lebensbewahrende Seraph an eine andere Kreatur gebunden ist, haben beide Kreaturen „Wenn diese Kreatur stirbt, kannst du sie zu Beginn deines nächsten Versorgungssegments unter der Kontrolle ihres Besitzers ins Spiel zurückbringen."
