I currently have the Amex Bonvoy Brilliant. I am trying to build up my Marriott balance with some card bonuses. Based on the application rules, I am eligible to apply for the Chase Bondless and the Amex Bevy; however, based on the various rules, it is difficult to hold one of these cards and then apply for the other. With each card issuer now offering three cards, I was wondering if anyone tried to simply apply cards at exactly the same time to circumvent some of the cross issuer rules (essentially you would be approved for each card before the other bank knows about it)
