I love card tricks. I know some easy tricks, and I've practiced some techniques like double lifts, fake cuts, card forces, Elmsley count, etc. I'm still not great with them, though. I only really care about card tricks that can be done with minimal or no preparation, and without any gimmick cards.
As for shuffling, my favourite way to do it is the tabled riffle shuffle. It's great because you get the thorough shuffle as with any kind of riffle shuffle, but without bending the cards. With overhand shuffling, I've found that instead of taking some cards and pushing them in the deck, it's easier to lift random cards from the pack and drop them on top. That way you won't cause wear on the edges. Card sleeves make overhand shuffling a lot easier as well. The sleeves create a sort of a wedge shape at the edges of the cards, so it's easy to push the cards inbetween each other.
