The safest way to prevent your opponent from stacking his or your deck is to have a judge come and shuffle.

To be honest, unless a judge is already watching from a far, which you can ask, you probably won't catch the act (as your opponent will probably deny it).

[Lythand]

Lets jsut say you are blatantly stacking your deck. As long as when you present it to your opponant, its randomized, there really isn't anything your opponant can do. If I remove lands and spells and stack the 2:1, then shuffle a bunch of times, as long as it looks "sufficiantly randomized" it should be good. I am aassuming at least.

[Trick]

Right. If you 2:1 then riffle shuffle a half dozen times it should count as sufficiently randomized. Just don't skimp on the randomization.

Rifle a couple times then my special version of shuffling, not pile, then mabey a pile shuffle then, radom card shuffle

i 2:1 shuffle and normally have 4-6 lands left, them i place them in random spots, riffle shuffle about 5 times them pile shuffle into 4 piles, then riffle shuffle 2-3 more times.  is that enough to get the randomization everyone is talking about. this guy at my tournament near me always makes a big deal about me beating him after the first time i beat him i have not since.  i always seem to mulligan down to 5 now i know what he is doing i am going to watch him carefully and soon he will understand cheating is not cool

When I used to play magic on the school yard, we had a little shuffling ritual. I was always the guy who lent people decks (precons), and I had this metal carrying case that I would take them in. Whenever I bought a new precon, we would empty out the box and lay out all the cards. Then I would throw the box into the air.

I still do this every round at every tournament.

I start of by cuting the deck in half and placing the two piles next to each other, stear on 'em for about 2 sec before i place my tumbs on the corners of each pile closest to me and each others, while my ring and middle finger is on the side furthest away. then then I lift up the half nearest to me with the tumbs and use the index finger to press the top middle part down. then I let the cards go with my tumbs, resulting that the cornes closest to me and each other are almost every other form each pile, before I let go of the cards and press them together using my hands. (i would guess that this has somewhat the same effect as riffle shuffeling:P) after repeating this 2-3 times I tend to riffle shuffle a few times before I allow my opponent to cut the deck.

[Eruditious]

I riffle 3 times, pile shuffle into 5 piles (without following a pattern, but putting one card on each pile each round of placement), then riffle 3 more times, then pile shuffle into 4 piles (random; same as above), then riffle once more and present.

i usualy pile shuffle(6), then rifle(1), then let my oponet split my deck if he/she chooses too.
