lmao@antinamesearch for a 3 character name. I'm not really sure why you'd want to avoid him seeing that anyway.. Wasn't defamatory or anything.
But yeah, Vex was the only one to really champion the fusion glitch as a legit strategy. I did consider him a top 5 ICs when he was maining them tho. So I mean.. Yeah. It can be used well. And most tourneys only have it soft banned. Like, it's unwritten in a lot of rulesets, so you should be able to use it at first, but if you start abusing it, it's entirely possible your local TO could ban it due primarily to the teleporting aspect. So I wouldn't focus your strategy around it. And if you don't focus around it, then you probably wont use it optimally, as it can be pretty tricky to use well. So it's just best not to bother with it imo.
Also, Aefice PM'd me asking about the snake mu and I wrote a pretty in depth response for him. It's pretty comprehensive and might be able to help other new ICs as well so I'm going to refine it a bit, add a little to it, then probably post it here.
