There are a couple ways to play orange.
1. The standard solid defense of just orange. This defense is fairly strong but has the downside of being only demons and most of the #/#'s on the characters are pretty high.
2. The Pale Green Magician/Orange defense. This was made possible by TexP and its shiny cards. This is a pretty solid defense and imo better then just solid orange at the moment.
3. Mass Demons with Orange being the foundation of the deck. This deck can cover pretty much any form of mass demon banding deck so this would go under Panic Demon decks and the Sort. This is a ok deck type but wont win you any tourneys unless if you know what your doing.
4. Orange/Pale Green place disease deck. The loads of place cards you can do and junk like that make it fun.
5. Demonic Stronghold deck. Throw in shadow and some other grey dudes with loads of orange guys and it can get very fun against fbtn decks.
6. The "deck manipulation" type is very hard to pull off imo. The goal of this deck is to place cards on the bottom of your deck then through Gates of Hell or some other orange cards bring these cards into battle and give you super cool cards and stuff.... Yeah ive never seen this type of deck pulled off. Not recomendeddededed.
7. There are also a plethora of different Dual Brigade decks that are nothing fancy and are very nice decks.
8. And finally, My personal favorite type of orange deck is the "Gates of Hell" deck. The goal of this deck is to discard your entire deck via Gates of Hell. The potential of this is that you can suprise your opponent by having 12+ EC's in your territory in one turn it also gets out your offense very fast. When paired with Tart. this can be very fun. But AOCP is the demise of this deck and makes me very sad when wandering spirit isnt in battle :p This deck type is very hard to use and is impossible to win with unless if you know how to play it. (Took a while to figure it out :p)
I think ive covered 90% of the deck types that are possible right with orange if any one has anything else to add fire away
If none of this makes sense dont worry because I dont know what I typed.... Ill clean up the post some more later
