Most Steel players would play around a ratio of 2-3 copies as this is not the kind of card you would like to see roll out in the early game but definitely want to see come the mid-game
The availability of high-powered mana-producing artifacts such as Black Lotus, Mana Vault, Sol Ring, and the original five Moxes and low-cost search and draw cards such as Demonic Consultation, Mystic Tutor, and Ancestral Recall result in fast-paced games that may not even last two turns
Recasting these with Karador, Ghost Chieftain can protect you turn after turn, as can reanimating them with Meren of Clan Nel Toth
Let me know in the comments or on the Draftsim Discord server
To my mind that is the same as playing something only for its card quality offerings
Neither of those cards are amazing, but jamming them both on to the same card is good, and really helps make a go-wide deck viable
