Eidolon, Weakened Hero

{2}: Eidolon gains your choice of deathtouch,
double strike, flying, haste, hexproof, indestructible, lifelink, menace, or trample until
end of turn. Activate this ability no more than 3
times per turn.
When Eidolon enters the battlefield, you may
search your library for an Endbringer card,
reveal it, and put it into your hand.
