Taylor,
I wouldn't say that a few card tricks constituted a 'routine' unless they were connected in some way.
To give you an idea, perhaps if you took out the 4 Aces and then did a trick with them, following it up with a transpo of the black to red Aces and then finished up with the spectators dealing out the Aces themselves that would constitute a routine.
Or if you strung (no pun intended) a few rope effects together, that would also constitute a routine.
But to do a card trick, followed by a coin trick followed by a rope trick wouldn't, unless you had a common theme to link them together.
Hope that helps.
And re the patter. You should never, ever use someone else's. The patter is what makes your version of McDonald's Aces different to mine. When you are learning a new trick you need to think and plan what your story will be to accompany the trick. That has to be your own, it has to suit you, otherwise it won't be you performing the effect.
Learning the patter is just as important as learning the trick, but one you buy and the other you develop.
I've developed patter which has been sold with effects, but you shouldn't just copy it word for word. Otherwise you are just a clone of me. Its there to start you off and to help you develop your own idea's for your own patter, to make the trick individual to you.
Developing your own patter is a very important part of maturing into a good magician

Steal a trick by all means, but put your own character into the patter, you'll be much happier in the long run.
Hope this points a few of the newbies in the right direction
