Sinister Sabatoge

House Dimir Spell
Level 3
Counterspell but succeed or fail you also Surveil.
Surveil: After a spell, you become acutely aware of every creature's position within 120 feet of you for a moment, almost like the blip on a radar. Creatures under the effect of a Mind Blank or a similar form of spell do not show up on the radar. (?)
