Some people suggest that if you are applying for CCs, that you should apply in sprees or multiples at the same time. That way they will see you credit score at the same time. If you apply every 6 months, your average age of accounts will be low when you keep applying for more credit (and if you are accepted). Thirdly, new CCs will draw hard pulls which count negatively against your score for the 1st year.
If you want to periodically apply for cards, I suggest waiting at least a year in between apps so that the hard pull doesn't negatively affect your score and so that your new CCs have some chance to age and you build some credit history with them. With cards with low $ CL, you will find it beneficial to pay more than once per month. This will keep you utilization % lower than paying once a month. Also, look at your statement date and make your payment a few days before then so that the issuer reports a $0 to the CRA for utilization. This will help with your credit score and will establish good habits for paying your debts.
Cheers.
Starting Score: EQ 732 October 2007; Current Score: EQ 839; TU 865, July 2022;I don't know about being blacklisted, at least not for an extended period. I applied for and receieved a very healthy CL for a card from MNBA which closed my account with a derogatory back in 2004. Since then my credit habits have matured and my score much higher so then saw me as fresh tasty meat! 
Once you stay in the garden and mature your cards you should be able to achieve 700 and 720 without too much effort which will make getting a mortgage easier. Once you get to that level, a 760 is within grasp.
As for the number of CCs, that's up to you but I read in a couple different forums that if have more than 50% of your cards utilized during any one month, it counts as a negative. I don't know that from personal experience but I recently went from 3 to 5 cards partly to test that idea. I plan to use no more than 2 cards every month (or make sure I PIF on the other cards before the statement date so that it shows 0 utilization).

1) That is encouraging to hear.
2) You know, for the last 3 years I have learned to live without any credit. And it's one of rare positive things going through hard times, BK ,etc.
So now I need credit cards just for the purpose of rebuilding credit , to get better rates for mortgage and auto loan. For now it's not problem to keep uti under 9%.
Does anyone know if the score goes up when BK hits 1 year mark ?
