Roadside Reliquary

A colorless source that spends its early life producing one mana and its late life cashing itself in for cards. The two-part draw is the interesting bit: it checks for artifacts and enchantments separately, so each clause is an independent yes-or-no, and a board carrying both turns a spent land into a two-card refill. This is not fixing (it only ever produces colorless), so it belongs in decks whose spells run on generic costs or whose color needs are already met elsewhere; the value it offers is not smoothing but a flood-insurance valve. Early it is a plain colorless producer that costs nothing beyond a slot in the manabase; later, once the board is developed and the extra colorless is redundant, it converts into the closest thing a land can offer to card advantage. The sacrifice cost is the honest part: paying two plus the tap plus the land itself means the draw is never free, and a deck that satisfies only one of the two checks is paying full price for a single card. That failure case is the tuning knob: the card only reaches its ceiling in builds already flush with both permanent types, and asks nothing of anyone else beyond a late-game exit. It sits in the long line of utility lands that trade manabase consistency for insurance against dead draws, here keyed to a specific pairing rather than any single permanent type.
