How to select one personalization experience from multiple options?

Hello,

I have customers with between 1 and 11 attributes that I'd like to use for personalization. I am trying to market a singular message toward each attribute. For a customer with multiple attributes, they will see one message at a time corresponding to one of their multiple attributes, but I'd like the message to change over time for customers with multiple attributes (either randomized or prioritized).

What's the best way to build this system? 11 experience targeting activities, one for each audience/attribute, where the activities have the same priority and expect the forced collision to present a random activity? Or is it better to use recommendations, which I am less familiar with? Something else?

Thank you
