Tallia, Ancient Reborn

Flying
Madness {x}{b}{b}{r}{r}
When Tallia enters the battlefield, if its Madness cost was paid, put a +1/+1 counter on each of up to X target vampires you control.
When Tallia attacks, exile the top two cards of your library. You may place vampire creatures exiled this way onto the battlefield tapped until end of turn.
