Jax

He's pretty OP right?

Matchmaking
Exhaustive scientific analysis has concluded that upon winning 10 games in a row, you will automatically be matched against a 5000 win Jax and your team will be "Bronze V wtf".

Sword of the Divine
A mythical item that 90% of the player base doesn't realize exists. Also, Only Jax can buy it. See: Oracle's Elixir

Viability Against Yordles
Jax can take out an entire team of well-equipped yordles with nothing but Ninja Tabi and the element of fear. Yordles beware.
