Convinced Riot trolls with the mm

I've been noticing patterns.. (FYI this is all in 3's games)

Never seen Galio before ever, in any game of mine.. ever.. in the 4 years I've played. I decide, alright.. I'm going to give him a go. Play a game with him, awesome, ok. Next game.. someone insta locks galio... are you shitting me? Ok, bizarre insane 1/100000 chance right? second game, someone else locks galio.....

I then decide to switch, alright, well I've not played or seen Yasuo in 3's then in over a year. Play 1 game with him, suddenly, I'm getting in games and he's picked or insta locked before me...... Now this is hitting problematic impossibilities...

I stop playing for a few days, and decide I'm going to pick up ekko, give him a go.. play 1 game.. I think you know where this is going.. second game, someone insta locks him again...

I've noticed this pattern where the MM seems to think its fking hilarious to grab someone with a high game rate with the last champion you played. This pattern has been happening with a 80% probability for the last month. That's in the realm of statistical impossibilities.
