If you mutate a creature on top of Sarkan the Masterless, you'll have a creature permanent
But Galadriel gives you like scry plus a half, maybe
Wrenn rarely ends the game alone, but it consistently sets up turns where burn spells, retrace effects, or graveyard recursion explode into massive tempo swings
You have a pretty small window to hit in which you actually see the seven-drop in the game but only draw it when you can cast it (or are at least close)
This means that youll never need to play any cards on your own turn again, In fact, you are actively discouraged from doing so as every opponent will draw a card during their turn making your cards one mana cheaper if you cast them on another players turn
