Eleonora, Violet Bloody Finger

Invader (whenever a creature with Invader attacks,
choose target creature an opponent controls to block it.
It can't be blocked by more than one creature.)

Whenever Eleonora deals combat damage to a player,
create a number of Blood Tokens equal to the
damage dealt.

Sacrifice five Blood Tokens: Search your library for a dragon creature card, and put it onto the battlefield
tapped.
