You can pick him when you want even 1st pick .If you play trynda enough you will win every mach up.
Do a fast analyse of Teams.
-Can you splitpush hard (possibility of camping by jungler who'll kill you)?
-Can you easily trade 1v1?
-Will you have hard time early ?
Then think now about your strategy, 2 options:
-Farm 'till death (just hit minions and tower + jungle) => Never trade or rarely
-Full tard trynda (trade as many as possible but care to minions they dmg hard) => Care to your farm

Farm all day (lane/jungle)
Care to ennemy jungler and mid when you over-extend, you are trynda , they WANT shutdown you as much as they can.

tower top down if you play well.
you got to farm your lane , ennemy jungle + your jungle

[Don't forget to ward ennemy blue buff if you're redside, behind ennemy redbuff if you're blueside.]

Split hard ,ask your team to play objectiv while you split cause you will be 1v2 / 1v3 everytime.
FUUCK LET YOUR TEAM 4v4 / 3v4 even if they kinda loose.
if you down inhib , you got 60% chance to win.
