Its no Mana Crypt, and while Im sure its overall price will go down, dont be expecting to pick this up for much cheaper than before
Penny sleeves just wont fit, unless you use oversize sleeves
Winds of Abandon takes that flexibility further by pivoting between spot removal and mass interaction depending on what you need, and the overloaded board wipe only costs 1 more mana than Fumigate
There are other cards that can help get you to an empty library as well (Demonic Consultation, Levler, and Ad Nauseam), in a singleton format, the redundancy is a huge asset
Thinking that the game is probably over, you let Seizan hit you for 2 more during your upkeep in exchange for a couple of additional cards
Ancient Tomb Rating: 8/10 Ancient Tomb is an all-star of Legacy and Vintage Cube
