hey I was wondering if someone can help me with my tink mu? i have trouble playing against him and i was wondering what i could do to beat him
It can be a pretty annoying matchup for Shulk. Projectiles and mobility, two of Shulk's biggest struggles... That said, your biggest advantage here is outranging Toon Link when it comes to melee, but half the battle is getting to him.
There's a few ways to approach him. First, Jump is amazing at closing distance and bypassing walls of projectiles. I'm sure you know that. Ironically, this is the least effective, because Sm4sh favors the lower ground. Still, it's an option, just try to make good landings, don't throw out N-Airs every time, it's okay to just land around them repeatedly without attacking to harass their personal space.
Speed is your best bet, running and shielding in bursts. It's a little tricky approaching horizontally, but if you get the hang of inching closer while blocking, you can slowly corner them or force them to try and jump around. Shield... I've found it works similarly to Speed. Just walk up to them blocking everything. It's pretty fun, really. Same as Speed, much slower pace, and you won't have to worry about your bubble shield much. You'll eventually reach them.
A big part of the matchup is just not getting impatient. It's easy to try and run in with a grab, or dive in from up high with N-Airs, but you have to sort of pressure their space until they'll play your game, because Shulk getting hasty is really punishable. Wade through projectiles until you're confident you can get the close range advantage, and try to stay around that space then.
It may be worth noting that Shulk can easily cut through Toon Link's projectiles with his aerials. It's not typically practical, but sometimes you can disrespect that boomerang throw you know is coming. And if your opponent gets very confident, don't forget about Back Slash and Vision. Back Slash can push your momentum that extra bit when they think they can punish your landing with an arrow, and such. Using Vision on projectiles at the right time can actually turn careless use of projectiles into a good way of 'manually' using Visions. Just remember it's punishable, too, despite being a great unblockable attack.
I mean... all this is general advice, but honestly, there's just not much Shulk can do against projectile heavy characters who play defensively. But basically, try to approach them from the ground. The main reason I say this is because aerial approaches are really easy to roll away from. If you try to jump towards them all the time, they can just rollrollroll and keep throwing things at you, so I think as a Shulk player, it's important to learn how to stay patient and make your way to an opponent from the ground. Especially the kind of (Toon) Link player that loves to try and roll away or past your when you start cornering them. Shulk's Down Smash is the god of roll punishing... and if they try to jump, you have all kinds of great aerials and Up Tilt to keep them pinned.
