Master Mirror

Flying, indestructible

Pay 6 life: Reveal cards from the top of your
library until you reveal four nonland cards. For each nonland card revealed this way, choose a player at random. That player may pay life equal to that
card's mana value. If a player does, exile that card
and they may draw a card. Put the rest into your hand.
Activate only during your turn and only twice
each turn.
