Despite what the tier list may say, this matchup is actually in Kirby's favor. You hear about the chaingrab and how it's awful, but the simple solution to avoid that is to not get grabbed. Stay out of her grab range. Make sure to put up plenty of f-air walls because those stop Sheik right in her tracks. Also, when you're in the air like that, you're where she can't grab you. If you're still having difficulties approaching Sheik, don't hesitate to use dash attack. Similar to Peach, dash attack is arguably Kirby's best move because it stays out for so long and has relatively large hitboxes. There's a useful tech that you can perform to grab instantly when you use it off a platform. I will provide a link that further explains this tech. Another useful strategy is to camp at the ledge and try to get a back throw off it.
Don't forget to use your unique ability to suck. Sucking is the key advantage you have here. Steal her needles with suck, then use them against her. Funnily enough, Kirby can actually use Sheik's needles better than Sheik herself can. His lower falling speed allows him to edgeguard better with them. It makes you wonder why Sakurai gave Sheik the needles instead of Kirby! Another reason why Kirby edgeguards Sheik more effectively than she edgeguards him is because Kirby's back aerial is better than Sheik's because it comes out faster and has a better launch angle than Sheik's. It's also stronger! His recovery is much better than Sheik's because he can jump FIVE times. It's also good because going out really far to edgeguard Sheik isn't a problem for him.
In conclusion, Sheik shouldn't give you much trouble. Just remember that all Sheik players are tier wh*res and don't hesitate to call your opponent that on the off chance that you lose the set. It's also great if you win because you can show off how good you are! You beat a Sheik with a low tier. Keep your head up Kirby mains, we will get our breakthrough some day!
