Spam Tryndamere and win at life. He's strong at all stages of the game and he's pretty simple. He doesn't even have any real counters since you don't even have to fight to win the game with this motherfucker. Not to mention that he's actually pretty versatile. You can build him the usual glass cannon, tank shredder, bruiser, backdoor overlord, split pusher, tank, on hit, or even fucking AP. You honestly can't go wrong with him.
Then there's Irelia. Basically tankier but deals as much damage as Tryndamere. The catch? She's "difficult". Yeah, fuck Irelia.
