http://wiki.cardhuntria.com/wiki/Cards/Lateral_Thinking As I remember long time ago this was probably only card that managed handicaps. And then never seen it used outside low ranked games and handicap quests. It's a niche human only skill and there is no single good item that has it. Today with more handicaps and cards like Radcannon it seems that more use could be possible, but the fact that common Purge does same and much more makes this card instead even weaker. Wouldn't it be nice to rework it a bit? Either completely rebuild it or add some extra effect, for example adding Cantrip would make it much more interesting. And truly, there could be other cards with similar problems, I'm just not eager enough to find out.
But now Purge purges all attachments on you, the beneficial ones as well. So Lateral Thinking can do something Purge cannot. And draw a card in the process
What if we changed Lateral Thinking to say: "Discard all cards attached to you unless they are Assist or Boost. Draw a card." Then it would do something more worthy of silver quality.
