The deck is pretty expensive now, though
This would be my personal choice for a goblin commander, though its less popular online than others ranked lower #1
You can still play it fairly by leveraging strong artifact payoffs like Urza, Lord High Artificer and Academy Manufactor, though you lose much of its potency
The draw and discard effects still take place if the creature is killed in response
About five years ago, those types of cards were much better since cubes were slower, but with many cubes adopting aggressive strategies and getting more efficient removal options, things like the Vindicate test (where you get an effect out of it if the creature dies at sorcery speed, so Consecrated Sphinx passes that test) hamper its effectiveness, but it does protect itself well if you are able to untap with it since you can turn just about any blue card into a counterspell or draw card
I'm sad to say when you open Edge of Eternities , you won't find any cosmic cards
