Actually if you go to http://sentinelsofthemultiverse.com/downloads and to a gander at all the Enhanced Edition changes there, it will give you a list of all the errata the occured between the original and the Enhanced Edition. Trust me there is a lot so it might be worth printing it off if you don't want to upgrade to the the EE. As a lot of cards really don't work like they used to. Infact all references to increase max HP are removed and turned to HP recovery instead.
