Bugs into mechanics

There´s been a history of some bugs in League that I know of that could work as healthy mechanics in the game for certain champions. When they came out at their specific time, people were curious to test them out and it turned out to be fun to do, they had a certain level of effectiveness but due to the specifics, they were hard to pull off. From season 4 I remember the Zed bug that allowed him to throw his Q mid shadow deploy turning into 2 shurikens thrown at different times instead of having to wait for the shadow to fully deploy and have both shurikens thrown at the same time. With just a day of testing, this mechanic gave zed some funny escape mechanics; if caught, he could use his shadow to run away, cast his q mid shadow, meaning the first one would come out of his body, but if he cast his W again really fast, the q would come out of his swapped shadow, making the second Q unexpectedly hit and surprise the attacker. People figured out lots of utility from this in the short time the bug was up and players were really mad because Riot removed it almost immediately. A couple of months ago, a Yasuo bug blew up in the community thanks to a Redmercy video, this "bug" had been there for a while but it was never really noticed by anyone. Now, I don´t remember if Riot removed this bug or if they stated that it was a bug, but it was certainly not stated as a mechanic since it was so god damn difficult to pull off and it didn´t always work. In the bug, Yasuo was able to extend how many players he ulted after the initial cast and during its entire duration. First, the requirements; he needed another teammate that had a knock up and he also needed to time the mechanic within the duration of his third Q before cast. To do this bug, a teammate needed to knock up someone on their team, the Yasuo had to cast his already charged tornado and immediately cast his ult, this would make it so that the tornado got casted from the Yasuo´s ulting position and not his original location. The interesting part though, is that the ult would start again in anyone that got hit by the tornado afterwards, and for the full duration. So far you have a mechanic that requires you to throw a skillshot from a changing position, a required enemy ulted by someone else in your team, the accuracy of your teammate to knock up someone, the split second you have to press ult while casting Q and all of that within the duration of your third Q before casting, now that´s a cool shit to witness that the game could use to spice shit up. I can´t remember all bugs, especially since I don´t play often, just recently I found out from the patch notes that Twitch was turning into stealth if he killed someone during the Q timer. I don´t know, but to me that seems like an interesting option for twitch to have, a high risk high reward decision to make. There are probably more bugs that I don´t know of but RIot should implement some of them in the actual game, or at least consider them. Obviously they are gonna have to be tweaked a little bit if they become too strong but most of them are pretty hard to pull of so it would be interesting to see them in the game.
