Spend a fortune to buy gold, change it to silver and buy as many cages and ointments as you can, even a bucket or 2, no matter the price, so that your hero stays fit as long as possible.
Get all of your friends and famlily to open an account to help you (those helping accounts are called "techs").
Make lots of raiding troops
Try to get a CP helmet, doesn't matter if it costs a fortune (like 1 million silver, or even more).
Repeat the following as often as possible
- Get those accounts to kill their heroes for you on oasis because you can't do it by yourself, then go with a few cages to get it cleared and ready to raid
- Raid the oasis.
you should be able to get your 2nd village very fast, and when your techs do, they can send you resources, provided that you get them in same alliance, or you can raid them if they are in another one.
This is how most of top players do this today. I am not a top player and won't do this because there is nothing to be proud about doing so.
