if I were to attach myself to a twitch would I also go invisible when he does? Was gonna pick Yuumi but Riot never put in her tooltip if she stealths with her allies. So i didn't pick her out of concern that i would be screwing over my teamate because of this.
Yes you would
Yes Yuumi is one of these perfect combos with twitch. you both become invisible and this opens a door for great surprise ambush. look at my last game Yuumi. Im getting a lot of S's with her and seems i will be reaching lvl 7 mastery with her soon at this rate.
also try veigar/ yuumi combo. will be terrible laneing phase but once both of you get rabadon the fun starts around here
Try this.
linked to any any champ not named 
, 
and
yuumi attaches to linked champ, kalista ults, Tk ults and you have a 4 man nesting doll.
Yuumi goes invis
im also getting a lot of s ranks with her not everyone is realizing just how op she actually is in the right hands. but that invis was something i wasnt sure about but now i know and thats awesome
Yuumi goes invisible with her champion, making invisibility even more of a nightmare to balance. It doesn't seem fair that she can just attach to a character and ult behind the enemy team, especially late game when her cooldowns are reduced. It would be more interesting if she had some different interaction with invisible characters, such as revealing them by attaching, or by being unable to attach if they were invisible, requiring some coordination around the fact that a team has an invisible character and a Yuumi.
