Masacre’s abilities state that when he is blocked his opponents suffer -50% ability accuracy if they have at least one debuff.

This has not functioned since his buff, it did prior to his buff. This is most easily evidenced by a champion’s ability to 100% parry him with the poison from Liquid Courage present.

And this can also be evidenced by Colossus’s normal combat power rate being present instead of his +100% combat power rate when his abilities are reduced below 100%.
You can see that while under lock on from Falcon Colossus gains twice as much power than he does from 4 hits into his block than he does while against Masacre with a debuff present.
