There's very little to dislike about Lumra, which is our pick for the best MTG Bloomburrow card
The expected value basically refers to the amount of value (in US dollars) you can expect to open from a booster box, on average
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
With that said
In all fairness, we did have a Modern Masters reprinting a few months ago, which is likely helping to keep prices in check, but at the same time, that's sort of the entire point
Anything that I missed
