In order to earn lots of money

1.) Always use the anti-attacks like /Slow/Stun/Etc

2.) Use Anti Skills like Envasion also

In order for everything to be easy and clean!

Well that is why I've given this kind of guide
Always get the de-buffer skills.

Example of your guide could be
Subzero

Kill player ASAP the faster way

well those tactics are different usable depending on which hero u have...so u cant have THE perfect strategy.
for example:
if u play as sonic,get his passive first and then his fire walk.(i really recommend to buy some boots as early as possible)
his norm attack gets a nice boost early in the game with it and creeping around is alot easier.

if u play as robin:
take her mass roots skill at first!
creeps are kinda useless against this skill so its very easy to kill them =)
