Yagoo, Avatars' Advocate

Other Avatar creatures and spells you control get
+1/+1 and can't be countered.
{5}: Look at the top five cards of your library.
You may put an Avatar or land card from among
those cards into your hand. If {w}{u}{b}{r}{g} was
spent to activate this ability, you may instead put
that card onto the battlefield. Put the rest on the bottom of your library in any order.
