Shilok, Arcane Sleuth

As Shilok enters the battlefield, choose a nonland
card name.
Reveal each card as you draw it. If it's the first
card you drew this turn and it doesn't have the
chosen name, investigate. If it has the chosen
name, Shilok deals 7 damage to target opponent,
choose another nonland card name, then that opponent fateseals 5.
