I like it in multiple attack brews, aggro, tokens, and alongside Commanders that share combat damage triggers that you already invest in unblockable infrastructure like Whispersilk Cloak
You could also drop a cool $100 for an Earthcraft and unlock one of Magic's easiest 2-card combos
Couple that with the utility of Leyline of the Void, Rest in Peace, Scavenging Ooze, Lion Sash, and even Graveyard Trespasser // Graveyard Glutton and it becomes that much harder to justify running this over the competition
Representing a scaling down of power levels common in many cards from The Dark, it can still devastate a deck that relies on creatures like Llanowar Elves or Birds Of Paradise to generate extra mana, destroying them en masse if they don't attack
Artifact Tutors: The Blue Mages Artifacts are omnipresent in Commander, and it would benefit a lot of decks to fetch some of them when needed
Some argue hes even enough of a Game Changer to go on that list alongside Kinnan and Grand Arbiter
