Recommendations for a replacement program for Print Explosion?

Can anyone recommend a replacement for Print Explosion? I used it for years (mostly to make greeting cards) until I upgraded my PowerMac G5 to a new iMac. Print Explosion is a 32 bit program and won't run. I've tried a couple apps on the app store but nothing has the range, clip art, and ease of use that Print Explosion had. Any ideas for an app that you love that easily makes greeting cards and has lots of templates and clip art? Thanks.
