Ready-Made Aster Idol

When Ready-Made Aster Idol enters the battlefield, Captivate X, where X is the number
of creatures named "Ready-Made Aster Idol" you control. (Exile X cards from the top of target
opponent's library. You may play any card exiled this
way until the end of turn, and spend mana as though
it were mana of any color to cast spells this way.)
{1}{u}{r}, {t}: target nonlegendary creature you
control becomes a copy of Ready-Made Aster
Idol.
