Friendly

From Archon Arcana - The KeyForge Wiki

If a card ability refers to a “friendly” game element, it refers to an element currently under the control of the same player.

Official rules v1.8 March 2021

Commentary

Based on the ruling for Nexus and Shard of Greed, a card that is being treated "as if it were yours" is considered to be friendly for the purposes of resolving the ability text.
