Gears 5 - Fast Method for Hi-Ho, Silverback Achievement

Fast and Easy method to unlocking Hi-Ho, Silverback Achievement for killing 200 enemies in Horde with the Silverback.
Forgot to mention, Aim for regular Juvies first, explosions kills do not count. That is a big reason I only gained 5% instead of 9%-10%
Setup:
Custom Horde - Set to Jingle Juvies on Wave 20.
Difficulty Beginner
