Seraphim of Ascendancy

Lifelink, flying
If you would gain life, you gain that much life
plus X instead, where X is Seraphim of
Ascendancy's power.
At the beginning of your end step, if your life
total is greater than your starting life total, put a
+1/+1 counter on Seraphim of Ascendancy.
To the old emperors, Eternal was just a word.
