Griffin Aerie
Enchantment
At the beginning of your end step, if you gained 3 or more life this turn, create a 2/2 white Griffin creature token with flying.
When griffins started nesting atop the northern tower, the castellan worried they'd be a nuisance. Instead, they took the entire castle under their protection.

Griffin Aerie's ability looks at how much life you've gained in the turn, even if it wasn't on the battlefield when you gained life. It doesn't care if you also lost life, even if you lost more life than you gained.
