Cax, The Rogue

Haste, Menace, Protection from elementals

When this creature enters the battlefield, each player must put "Perdition's Blade" from their hand onto the battlefield attached to Cax, The Rogue.
If they do, they draw a card. If no "Perdition's Blade" is put onto the battlefield this way, search your library and graveyard for a card named "Perdition's Blade" and put it onto the battlefield attached to "Cax, The Rogue".
