With new Yog pack you can use:
Scholar from Yith -> Frozen Time
And its less stupid than it sounds when you run Yog mill deck
Blanked Forgotten Shoggoth might even happen in real game now.
And placing Yhtians in discad pile or deck might decide a win if Interselar migration happens to be close to deck size.
That's why i hate "it doesn't matter in current card pool" ruling arguments.
