Poseidons Last Wish

Look at the top ten cards of your library. You
may exile three permanent cards among them.
Put the rest into your graveyard. Target
legendary creature you control has all activated
and passive abilities from permanents exiled with Poseidons Last Wish.
At the beginning of your upkeep, shuffle a card
exiled with Poseidons Last Wish back into your library. When there are no cards left that are
exiled this way, exile that creature.
