There are a ton of combos. Here is what I suggest to help you research.

Go to the Breeding Sandbox. Click on the "Combo Finder" tab and enter Rainbow. It will show you all the possible combos. In the chart you will see a column called "Min/Max Wait". That indicates the longest time for any dragon OTHER than the Rainbow. So, for example, it shows "Current/Flower" with 0.5/9. That means that the shortest fail would be 30 minutes (Poison or Cactus) and the longest would be 9 hours (Swamp). By choosing combos that have fewer than 48 hours in the second "Wait" time, you know you can't get any other 48 hour dragon except Rainbow.
