Sinistre sabotage

A spell that can't be countered is a legal target for Sinister Sabotage. The spell won't be countered when Sinister Sabotage resolves, but you'll still surveil 1.

Some spells that instruct you to surveil require targets. You can't cast a spell without choosing legal targets. If all of those targets become illegal, the spell doesn't resolve and you won't surveil.

You perform the actions stated on a card in sequence. For some spells and abilities, you'll surveil last. For others, you'll surveil and then perform other actions.
