AI and custom decks

Hey everyone, I've just recently discovered this site and the mods for duels 2014, and I've downloaded the community wad as well as the deck builder tool and made some custom decks. However whenever I try to play a game against the AI where it is using one of the decks I made, the AI doesnt seem to know what to do at all, as it would just play the lands but not play anything else from its hand. For example, he had four lands untapped and a Siege Rhino in hand, but did nothing that turn and ended up discarding the Siege Rhino. Anyone can help me with this?
Thanks!
Thanks!
