Deepspawn Skaab

As an additional cost to cast Deepspawn Skaab, exile a creature card from your graveyard.
When Deepspawn Skaab enters the battlefield, look at the bottom two cards of your library, then put any number of them on the top of your library and the rest on bottom in any order.
"These Deep Ones make wonderful skaabs; clearly I must become a fisherman." - Ludevic of Ulm
