Kanta - it depends on what assists nova and mags are running. Solo nova vs solo mags? I’m biased but that’s at least a 5/5. But if you’re talking like, nova/bolts vs. mag/missiles, it’s not going to be pretty. Still doable, but just… not going to be pretty
cheech - plasma isn’t the assist to be running for crazy ambiguous resets/welcome mixups. If spaced right, it’s great for catching buttons on incoming, and is hit confirmable. As far as your mixup game goes, magnus is capable of doing some cheap shit alllllll by himself, but you have to make them scared of the mixup. Why respect your mixups if they aren’t scary?
Learn your meaties. Learn pseudo-guard breaks with j. L. Be aware of what mags is capable with as far as actual guard breaks are concerned. Learn your left rights. Your opponent needs to fear the mixup and be scared to press buttons, otherwise you already lost the incoming hit.
Especially with someone I haven’t played before, and even with people I play often, I like to test the waters. For the first incoming mixup I almost ALWAYS hit them meaty. It lets me know if they’re the kind of player that likes their buttons, or if they are actually going to block. Even if the meaty doesn’t hit, a good setup leaves them in grounded blockstun for a follow-up mixup. If the meaty does hit, kill off the character.
By doing that, your opponent is now genuinely scared of your mixup. You outplayed their point character, and when they attempted air mobility/helmbreaker/whatever it was that they tried on incoming, it cost them another character. Their anchor is now waiting for his welcome mixup, and I can guarantee in this situation, 9 times out of 10, they aren’t going to press SHIT. This is right where you want them, because now you can attempt pseudo-guard breaks, left/rights etc., on incoming without too much fear of getting bopped by buttons.
Moral of the story: Assists are just a tool to assist your mixups. Your mixup potential and meta-game with mags come from you, and you alone. Make your opponent fear the mixup. Then, give them a good reason to be scared.
