Whilst combos are important, you can also pop this trophy using the drill. Equip the Carl mask which gives you a drill at the start. Take your time, knock down enemies and then execute with the drill.
Remember to use doors and you can also throw the drill to knock enemies down. Firing guns to lure enemies is also a useful trick.
The drill execution leaves you vulnerable for a good chunk of time so be patient. The drill is useless on big enemies and dogs.
Credits to youtuber TheSeraphim17, with his method I got this trophy so much faster.
