Hi there, and welcome on my guide to playing yuumi. First thing I'd like to mention is that yummi has some complexity and isn't that go afk and set a macro to e champion that she is often known as. She requires lots of micro managing of yourself and your team to make sure you're at the right place at the right times to spread the love and the heals to all your team.

For early game, your team will be fighting a 4v5 until 10-12 minutes, you will barely matter with your minuscule healing. You start off with 400 base mana and your zoomies cost 100 mana, meaning with early mana regen, you have roughly 4-6 heals that barely heal at all before you have to recall. This is where your passive and biscuit delivery come into play. Biscuits, I would only use when I'm really low on mana and I have some missing health, this will regen your health and give you more max mana. In addition, your passive rewards you for being aggressive and getting that poke with a shield and enough mana for another heal. Use your passive as much as you can because it will give you and your adc more sustain in lane to gain a cs advantage and some more items for late game. Use your Q to snuff out bush hiders and supports that get too nosey for your whiskers. You are a support that doesn't have much utility like hook champions so you gotta make sure your team knows you matter and heal them real good.

Now that you've gotten one or two items under your belt, your heals do much more healing, you have less mana problems because you start having more max mana and a lot of mana regen. At this point, you'll have a teammate that's usually more ahead than the others (if it's the adc, you're doing your job). Stick close to that person because you overpower them even more, but don't neglect your other allies, this is a team game, if you're fighting a 2v5, you're going to lose.

Now, you've entered supersane, you've achieved ultimate prowl potential. You're a little kitty cat short and stout, here's your tail and here's your snout. At this point if you mess with the cat, you're gonna get scratched. You're nearly full build by now and your gathering storm is giving you even more healing than before. At this point, pretty much any champion can burst you down so don't get off your team as often for your passive. However, you can be the the reason your team wins a team fight so spread the heals evenly throughout your team but focus on the tanks that are taking all that damage. You've reached peak kitty, rengar doesn't even compare.

In total, yuumi isn't an amazing support, but if you get her down, she's a lot of fun to play. I hope this guide was helpful and thank you for reading all the way through. Hope to see you on the rift...
