Favored of Iroas
Creature — Human Soldier
Constellation — Whenever an enchantment you control enters, this creature gains double strike until end of turn. (It deals both first-strike and regular combat damage.)
"The promise of victory fills my heart. There is no room for fear."

Rulings
Multiple instances of double strike on the same creature are redundant.

An Aura spell that has an illegal target when it tries to resolve doesn't resolve and is instead put into its owner's graveyard. It doesn't enter the battlefield, so constellation abilities don't trigger.

A constellation ability triggers whenever an enchantment enters the battlefield under your control for any reason. Enchantments with other card types, such as enchantment creatures, will also cause constellation abilities to trigger.
