how would you run the orng demons?
Well, that depends on what you are going for. Are you looking for the Wandering Spirit/Gates of Hell style of running them, the chump block style, the big band style, the mixed with magicians style, or another? Since you just mentioned Orange Demons, I'll assume the first one.
First, start with
The Gates of Hell (GoH), which lets you discard the bottom card of your deck (at any time, more or less). Orange demons go to play, along with Souls, and the rest are just discarded. This is where
Wandering Spirit (WS) comes into play. He pulls a demon from the bottom of deck (this will let you use non-orange in the combo being described, note), CBN bands to generic demons, and he makes it so that any of your demons discarded during the battle phase just go beneath your deck instead. Note also that any discarded at the same time would be placed in an order decided by you.
So, what you do is have WS block while GoH are active. Then you band to someone like
Spirit of Temptation(SoT) (which also has the added benefit of letting you set your bottom card) and band to someone else (usually their EC when available, or to whatever defense you paired orange with otherwise). Whatever you do with the chain, if you end up getting discarded (by special abilities, the numbers, or your own chump block), all those demons in battle go to the bottom of your deck. You choose WS to go on the very bottom, your next link (like SoT) right above him, and any others further up. ALWAYS put Orange below any other brigade demons. Next time you are attacked, they are waiting nice and safe down there, so you activate (GoH prior to blocking), bringing WS up. If the next card is an orange demon, do it again. Repeat until you know there is no more orange. Now, block with WS, which lets you bring up an off-colored demon if there is one on the bottom.
Band, rinse, repeat.
So, some combos. You can use play-first weapons on humans, or small numbers (to get initiative), to play cards like
Death of Unrighteous or
Belshazzar's Banquet. Your demons are discarded too, but they go to the bottom of your deck for another block. You can also use the
Trembling Demon combo. If you use him while
Holy of Holies is active, the last part of the ability is negated, meaning your opponent cannot discard a card to negate him. If you are smaller than the heroes (putting Holy of Holies in a temple while having
Crown of Thorns active as well makes this almost too easy), you can decide to lose by the numbers, discard the demons (who go to the bottom of deck, with Trembling right above WS), then next time you are attacked they come out and repeat the process ad infinitum.
But essentially, "running orange demons" usually involves getting WS and GoH out, then having your demons keep coming back to do annoying things until your opponent
quits in frustration runs out of cards to hit you. It doesn't work all that well in T1 unless you get very lucky, but it is a fun defense to me.
