What is the best card to supplement AMEX Explorer?

I have decided to get an AMEX Explorer which I have assessed best suits my needs. The only thing is AMEX is not accepted everywhere. I will be using it for the bulk of my transactions. Is there a suggestion for a supplementary card with rewards, that doesn’t have a big limit or large annual fee to support my points earning food the Amex Explorer.
