Even discounting Skullclamp ($1.99) and Sol Ring (which is in every Commander 2017 deck but, as the most played card in Commander, is still worth $3.27, even with a ton of reprintings), the Vampire deck is overflowing with artifact value, with Door of Destinies being the single most valuable colorless card in in Commander 2017 at just under $6, along with Well of Lost Dreams and Blade of the Bloodchief, both coming in between $3 and $4
