Lakos, Marshland Scourge

Whenever you cast a creature spell, you may
search your library for a creature card that shares
a converted mana cost with it, reveal it, put it
into your hand, then shuffle your library.
Creature cards in your graveyard have jump-scare.
(You may cast those cards from your graveyard as
though they had flash by discarding a card with the
same converted mana cost as those cards in addition
to paying their other costs.)
