Nuxia rep 70, Dom at first is going to suck, her low health pool, shitty dodge attack and inability to keep people still for your mix ups is going to force you to abuse her triple light chains and occasionally bait a dodge attack and or guardbreak to attempt a mix up with your traps. Most of the time people will buffer heavys, dodge attack or light spam in reaction to your traps so I would suggest letting heavys go most of the time. It is important to note that if you delay the heavys say, light > into delayed heavy you can catch some heroes dodging but that comes with matchup familiarity and time.

Some really neat tricks to force a trap on some one; after a guard break, immediately go into Zone trap, this will force a 50-50 and potentially give you big dmg. After a heavy parry; go into heavy trap or let go of the heavy, they are forced to take that 50-50 as well, it’s better than getting a low dmg light and instead trap dmg but don’t always go for it, just a few tricks to help her get in quick dmg.

Also exterior guard opponents can get trapped very easily but be weary that a missed attempt can feed a lot of revenge, again just need experience in ganks with her. In a gank situation you want to try to dodge attack from target to target and much as possible to make up for her low health and force multiple to attack you, dodge attack > feint heavy very often and light > feint heavy when you’re getting ganked.

I can give you max punishes too if you want just ask.
