I can honestly say that DeckOne is one of my all time favorite decks! They work beautifully and the box is art in itself! The Rice Papers is good but a little different, that being the tricks on it aren't really tricks you say, "Hey let me show you a trick real quick" they're more like the things you would do in between tricks. Just random acts of crazy magic happening at random.
Example, if you were to perform an effect where you need the spectator to sign a card, you would pull a sharpie out and when you uncap and recap the sharpie it becomes a small sharpie then a big sharpie. Things like that. It's a very different kind of magic dvd.
And as for the Saturday Night Contests, the rules and prizes are posted here in the forums in the General Discussions section. You'll know what it is because the topic is called, "Saturday Night Contest".
Basically depending on what the contest is, you may need to record a video of something and you upload it to youtube or any major video sharing site and you post the video in the contest posts. Just follow the rules that they give you and you will be fine.
I hope this helped. If you have any more questions, feel free to ask me anything!
