Imbued

Enchantment

This card is played automatically at the start of each combat.

An Imbued Skill plays itself at the start of your first turn in every combat.

Setup: at combat start it is sent to the bottom of your draw pile, staying out of your opening hand.
Auto-play: the auto-play phase fires it for free, no Energy spent, an enemy-targeting Skill picks a random enemy, and the opening hand is already drawn, so effects on cards in hand see it.
After: it then goes to the discard pile, or exhausts if it has Exhaust. Only Skills qualify.
Source: Electric Shrymp, an Ancient relic from Orobas in the Hive, enchants one Skill on pickup.
Order: Whispering Earring grants nothing here but runs right after Imbued, so Vakuu's first turn sees what it set up.
