Vault of Transcendence

Hexproof, indestructible
At the beginning of your upkeep, for each player, you choose whether that player loses 1 life or gains 1 life, then draws a card or discards a card. Then, if all players' life totals are equal,
and all players have the same number of cards in hand, exile Vault of Transcendence, then return
it to the battlefield transformed.
"Balance must be had."
