Cards like Sharuum the Hegemon and Hanna, Ship's Navigator provide graveyard synergy as a secondary strategy to retrieve the artifacts you sacrificed to Breya, Etherium Shaper
Now you can use either card to make your abilities trigger an extra time, adding a layer of resiliency and consistency to your deck that wouldnt be there if you just relied on Elesh Norn
It's a great creature for any format where graveyard recursion is a viable strategy, such as Commander, Modern, and Legacy
Youll get two 20-card tutorial decks, eight themed half-decks, two playboards, two spindown life counters, learn-to-play guides, tokens, and a rules reference booklet
None of its effects are ridiculously overpowered but its flexibility is what makes it a good card
You can also use it to fix your colors, snag some utility lands, or even just ramp
