Did this on my Defender Titan. Usually use suppressor grenades but it definitely takes some practice. Like the flash bang without blinding effect. The magnet grenades do have trouble sticking at times, I think It sticks better when thrown a certain distance. Besides that just whatever weapons you're most comfortable with. Void Sniper or shotgun depending on map and how your opponents are playing. Knowing how the opposing team is playing is probably the most important part. Fight with your team instead of 1v1. Run if the situation isn't in your favor. Good luck!
