Since Season 10 is pretty much the best season in terms of player quality and awesome features such as jetpack, I decided to go out on a limb and spend some time constructing a guide on how players of all skill levels can squeeze into Onyx.
First, you're going to need a secondary account. A close friend will also need a second account. On each of these accounts, you will effectively 'derank', thus joining the recent Iron boosting fad which every single retard seems to be doing this season. (Only one of the 1% players this season is 'legit'.)
Step 1: Search with your friend for a few games, you on your main and him on his Iron. After a couple of wins, rotate so each of you can have their turn at being boosted.
Step 2: The most important step of all. JETPACK. It is well known that jetpack abuse is the key to being a good player.
Step 3: ????
Step 4: Profit. Awesome game mechanics such as 2s-tricking can also be utilised to maximise profit.
Hope this helped.
