The Old Everwyrm

Trample
When you cast The Old Everwyrm, search your library for a card named Shara Ishvalda, Unearthed and exile it. When The Old Everwyrm dies or is otherwise removed from play, you may cast Shara Ishvalda, Unearthed from exile without paying its mana cost.
When this creature dies, create 3 Monster Materials.
