Sadly, it is the basic, farming gold.
At the same time, you farm for gold, then you get the possibility 0-1 to get a mix box to help level up.
No matter if people say to use the BASE, in order to use the base, you need to farm. The BASE complements a rushing way to develop with the cost of massive farming to get power kits as one example.
The other option is to use real money and buy gold, boxes etc.
If you are looking to get 200 parts myth in a few months, well...... takes long even for a daily 7 days a week farmer and even buying stuff.
Save tokens and use them properly. Look for proper offer not just buying an offer to rush. Have to think.
