played Illuminate…selected Gift of Luminance. Next card off my deck was Mass Dispel. What happened to Gift of Luminance? Also have picture of the issue…but don’t see a way to add to this post.
After you played Illuminate, but before you drew the next card, you (or your opponent) played some card that shuffled your deck.
There is a sticky post at the top of this forum titled “How to share links to screenshots, videos, and replays”.
