A lot of people will note that I've mentioned that I have multiple accounts. Some people frown on this saying it's unfair, others accept it as part of the game. Both are kind of right.
It used to be people would make 100s of accounts the day a referral card was listed, level them all to 10 using some sort of bot, then trade all the resources to a main account. This was shady. I don not condone or support such activity because it's game breaking.
I DO condone creating however many accounts you will actually PLAY. For most people this is two to three. I myself currently have two, but will be creating a stamina account as my third. I play both accounts regularly enough to be in a top 300 Order on one, and a top 150 order on the other. Neither account is useful during stamina events...QQ.
Each account should be viewed like a business. Starting one from scratch was expensive, but is finally yielding something. To start the second one you should transfer resources to speed up its progress, accepting that although you'll go negative at start it will result in higher yields in the long run.
There are some rules I advise when creating a second account (A non stamina account):
Rule 1: Treat it as a main account.
-By treating the account as a main account, you create value for it. Your actual main account should virtually be on auto pilot leaving time available for the second account. Think of it like a business, once your main building is up and running smoothly, you go to your second to run it and make sure it runs smoothly.
Rule 2: Do not steal from your second account.
-Do not use HP from your second account to feed your first account. The HP you earn on your second account should be used to progress the account. Sometimes you can take from your first account for your second, but you should never take from your weaker account unless it's absolutely necessary.
Rule 3: Transfer cards, HP, CW over to account number two.
-You will progress faster if you have a decent deck, hp, and cw. I'm not talking about great cards, but for example I had four DK Lucy's sitting around and two full evo rares that went to my second account. I gave the account 50HP and 20CW to start. Because I did this, there was no need for me to spend HP on cards, allowing me to accumulate HP fast on account number two. Also by having a decent deck at a low level and a willingness to blow 50HP on a Holy War, I managed to enter a decent order.
Rule 4: Friend your main account
-This gives you the ability to trade and utilize your bazaar tickets and cards to maximize profits. Pretty self explanatory.
If you do this, eventually you will have two higher level accounts that will get double rewards doing HW and the ability to transfer HP/CW cards between them to help them both.
Stamina Accounts: A stamina account is necessary for stamina based events as well as gaining feeders for your main account. Only a single stamina account is necessary as the events are so competitive that splitting your resources is expensive and difficult. Make sure to leave enough attack/defense for one attack and one defend, otherwise gaining treasures during the event are a pain.
Power Leveling Accounts: To power level an account the easiest method is to place all points into stamina. I normally recommend getting around 300 stamina. If you push it a lot past you won't be able to drop it down to 150 easily. Use CW to level quickly.
Reallocating points: Hard way is to remove fellows yourself, suffering additional point losses if you do more than one in a day. Easy way is to have people unfellow you. If they refuse just keep sending them stupid trades for being dicks.
Logging in and out: Swapping between accounts on a single device is easily done by force stopping the application and clearing cache. You will be able to log into the alternate account. Of course the account won't be registered.
Registering a second account: I'm sure you have a parent, friend, sibling that has a smart phone or tablet that doesn't play, once authenticated, the account can be accessed from any device. There are other ways but I'm not going into them, they are shady. Google it.
The advantages of having multiple accounts should be obvious. You get multiple login rewards, multiple HW rewards, extra bazaar tickets, and easy access to feeders. On top of this it's almost necessary in order to have an account that can do well during stamina based events. Just remember, each account needs attention.
