Dr. Mundo is a simple champion to play with basic mechanics and very strong mid-game, Dr. Mundo Is anti-tank tank, he does jg pretty easily and counters a lot of champions, he is not the best at doing damage but one the best at enduring fights.

Dr.Mundo will die pretty easily in an early 1v1 all win, to win against an melee match up try hitting your target it your Q from a distance until he is about half life, wait for him to be close enough and then go for the all win, Ignite will be pretty useful against Flash, when you reach level 6, then you will be able to massacre your enemies, use only at emergencies or about half life, your ultimate can also save you from enemy jg ganks, it sure saved me a lot of times, Mundo can destroy towers pretty easily, I'am often the one to destroy the first tower, as soon as I destroy the first tower I go Mid lane to gank and help destroy the tower. Remember, Good Early Game = Good Late game, If you're able to do this, the match is already won.
