Kara Songfist

Whenever you sacrifice a Saga, gain an
experience counter.
Bard creatures you control get +1/+1 for each experience counter you have.
Whenever Kara Songfist deals damage to a
creature or player you may pay {1}{u}{g}. If you
do, search your library for a Saga card with a converted mana cost equal to or less than the
damage dealt and put it onto the battlefield
under your control. If you searched your library
this way, shuffle.
