The blue counterpart to Wheel of Fortune, this card not only refills your hand but can shuffle your yard back into your library, giving you access to all of your cards again
If your deck is aggressive this is not a great tool and if you have few low value recursion targets this will also under perform although will at least remain playable
You may want to start by spreading out poison counters and making sure theres at least one on each opponent to maximize your proliferation effects
Mono-blue limits what you can do with Grazilaxx, but theres some fun to be had with ninjas, cards like Faerie Seer, and Archaeomancer/Ghostly Flicker loops
Because it has prowess, whenever I cast a noncreature spell, it will get +1/+1 until end of turn
Both are pretty nice here
