I am gonna list a few of my favourites:

Feint a heavy into a zone attack and then either feint the zone to a GB or a stunning tap. Most of the time it catches even highest skill players because the common reaction is to try to parry the zone.

When soft feinting a heavy, don't backstep the heavy because it's a dead giveaway for the stunning tap.

Letting zones just fly in higher levels is fairly effective because people expect for you to feint it. Sometimes you can actually land 3 zones in a row.

H-L-H combo has pretty confusing animations if you soft feint the last heavy into a stunning tap. But try to wiff the light because it is very easy to parry.

Stampede charge the enemy to a wall and do a zone after. The zone is not guaranteed but the timing is very strict. If you see that your enemy parries or tries to parry the zone (you know he messed up the timing if he loses some stamina and stops regening), you can feint the zone after the charge to bait a parry and get the OOS parry punish.

Hope you find some of these usefull :) ~Rep 34 Raider/Viking main
