I believe renekton is an ideal choice for anyone wanting to climb elo quickly and easily in the top lane. He is simple to learn and has a high reward for when you do master him. He has heeps of damage if played right and easily can get out of sticky situations with his Slice and Dice ability (E)

Early Game (Levels 1-9) Can play a huge factor on how the rest of the game plays out. It is important to play safe until you hit level 3 alot of renektons damage comes from his w and because of this level 1-2 renekton is not very strong. Before hitting level 3 poke the laner as much as you can using your first E to approach them. Q them and E back out. Make sure to hit something with your E when going in or else you wont be able to proc it again to get out. Once you hit level 3. Try to look for an openning to all in. First blood is very important because you need to get an early lead. A combo i like to use early game is E -> Auto -> W -> Ignite -> Auto -> Q. Remeber to keep the second e for a gap closer when they try to flash away. After getting first blood. Push the wave in and back this is so you can put your lead to good use.

Mid game is when renekton really goes ham. Make sure to roam and farm alot to keep the lead in late game.
