Shurit, Nekros Strategist

If Shurit, Nekros Strategist is sacrificed as an
addition cost for a spell you cast, and that
spell would put a Nekroz creature with Ritual
onto the battlefield, you may replace the
additional cost of the spell with just this creature.
If this creature is sacrificed, you may search your
library for a Nekroz creature, reveal it, put it in
your hand, then shuffle your library.
