Shadowmeld Infiltrator

Whenever Shadowmeld Infiltrator
deals combat damage to a player, you may
surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard
and the rest on top of your library in any order.)
{4}{u}{b}: Return Shadowmeld Infiltrator from
your graveyard to your hand.
Activate this ability only any time you could cast a sorcery.
"A master of shadows, their presence undetected, their motives veiled in secrecy."
