Yeah, I got about 135k points on Huekaiser, so I may have some decent knowledge on how to build/fight enemy laners.
LANERS
TEEMO - Nothing you can do in this lane. I max W first for this lane just for the sustain. Go to wolves/krugs to get a ginormous heal and go back to lane. I rush Visage if the lane really sucks, but ask for ganks, free lane, and avoid poke/trades.
DARIUS - Skill matchup, but you have the upper hand early game. Level 1 he can bush cheese you, and never walk up to him without being confident you can destroy him. Also be very catious when getting to level 6. If he gets it before you and all-ins you, expect to be dunked. Rush Rylai's and if he face tanks your damage/dodge his heal and you heal, he loses very hard. Your passive can do wonders. Max W first than Q.
TLDR; avoid his heal, watch for level 1 or 6 cheese, poke with your E early and you'll win
Ekko - Haha. Once he loses his slow on his passive, he will be MUCH easier to deal with. Avoid his Q and stun, and just farm up since you can't really kill him unless he is stupid. Max W and watch him cry as you heal for all of his burst!
Garen - From my lane, this is a STUPID easy lane. He has a silence, but if you keep range and he tries to run up to you to QE, just activate all your abilities and demolish him. Your passive blocks pretty much all of his damage. Care for his level 6 execute. I can only imagine this lane sucking if he Qs you and you don't activate your abilities
TLDR; Out sustain, out range, out damage, out tank, out utilize, out lane, out teamfight, out scale.
RUNES/MASTERIES
I take:
9x magic pen marks
5x armor seals
4x scaling HP seals
9x scaling AP glyphs
3x MS quints
OR...
take 9x AP glyphs and 3x AP quints, start dark seal, take ignite flash and Deathfire touch and level 1 100-0 people.
I go 0/18/12 taking Stormraiders for the movement speed boost and slow reduction for great early trades and glueing to people.
18/0/12 is also pretty good, DFT brings some nifty damage and magic pen to hurt more throughout the game.
BUILDS
I build Rylai's, Merc's/Tabi boots, Visage, Deadman's/Sunfire, Void staff, and Zzrot. Great damage all around, more healing and better map pressure.
Any questions, feel free to ask.
