Blacklist

Choose three spells of 5th level or lower that you know and transcribe them on your blacklist. For the duration, when a creature other than you that you can see casts one of these spells at 5th level or lower using any components that you recognize as part of the spell's casting, the spell automatically fails, as if counterspelled. 

If the spell is cast at a level greater than 5th, you can use your reaction to make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell fails and has no effect.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the interrupted spell has no effect if its level is less than or equal to the level of the spell slot you used, and you may increase the number of spells on your blacklist by 1 for each level.
