Quite good, but one detractor – Randominion - Dominion Card Randomizer Review

Though second edition sets are an option, the app does not allow selection of both first and second editions simultaneously. For those that have been playing Dominion for many years, having both editions of the base game and Intrigue is common, as is the practice of adding the second edition cards rather than replacing the first edition versions.
