No patch necessary, just install and play.
The level of depth you can get with multiple heroes to choose from and the combinations you can put together make this a very fun pick me up deckbuilder. the DLC adds some more difficult modifiers into the mix, which is great. Honestly my one con with this game is the DLC hero you get, it just seems a bit underwhelming, but apart from this great game I would recommend to anyone familiar with the genre
