Tyranids Maleceptor vs Deathwing Terminators

Hey! Played 1k game today vs tyranids. The most demoralizing thing was Maleceptor that vanished two 5 man squads of Deathwing Terminators in 2 shooting phases. How to counter this? Or this matchup just bad for the Deathwing? I had 10 termies, 5 Deathwing knights, Belial, Redemptor Dreadnought and 5 Intercessors but could not do almost anything. I had a good charg with knights after deepstricking on Teleport Homer but that didn’t help:)
