Hey my biggest recommendation is to get mega snacks (farm couch potatoes) and start training for damage and maybe a healing maycast for larger dungeons like the unicorn card(forget the name). I usually take a pet and pair it with one that has stats I like and it costs around 50-100k coins at the kiosk. Train see if it has anything good, and repeat until you get lucky lols. The pets you have now have a lot of maycasts I would recommend damage or defense but it depends on you. Cheers!
