Veli, Sanctuary Searcher

Hideaway (This creature enters the battlefield tapped.
When it does, look at the top four cards of your library,
exile one face down, then put the rest on the bottom of
your library.)
{g/w}: Until end of turn, each Ally creature card
you own has hideaway.
Whenever an Ally you control attacks, you may
put a card exiled with it into its owner's hand.
