However, Id like to warn you about the dangers of running all basic lands in a multicolor deck
Being +EV before the inevitable price crash is the bare minimum threshold to pass question 1, but considering there are 52 unspoiled rares and value uncommons like Eternal Witness and Kitchen Finks it seems likely that UMA, even without the Box Topper, will pass that check with flying colors
There are two versions of packaging you can find for these decks: the full-color box and a minimal-packaging version found online
Unlike draft boosters, collector's have a significantly higher number of rare and mythic rare cards, with a guaranteed five in each pack
A couple of standouts are Teferi, Master of Time who will quickly become BFFs with Sefris given a chance, and Enduring Renewal, which we can play out once we have a creature or two in play and ensure we draw straight through to our lands/noncreature interaction every turn thereafter
Aetherdrift $270.46 Aetherdrift has its haters, but theres plenty to love in its card slots
