Keaton's Eidolon

Flying, vigilance
Other Spirit creatures you control get +1/+1.
When Keaton's Eidolon enters the battlefield,
you may search your library and/or graveyard
for a card named Keaton, Conjurer Magnum,
reveal it, and put it into your hand. If you search
your library this way, shuffle it.
Wise as the Life itself, it guides the lost ones
and strengthens the righteous ones.
