That is the literal definition of USC - Cheating. If he was just shuffling badly without knowing it, it'd be Tournament Error - Insufficient Shuffling, which is a Warning.

But that is a judgement call right? He didn't admit to points 2 and 3.

With fewer than 6 mash shuffles, the initial order of the cards in your deck cannot be reversed. Since not all orderings of cards are even possible, the deck 100% objectively isn't randomized.

Mash shuffles are either a poo poo riffle shuffle or are just poo poo, there's much more variation from how you actually do the shuffle than in other methods (ie it is much more likely to be clumpy than a riffle shuffle and therefore pretty terrible, but if you do it "properly" then it's essentially the same as a riffle shuffle).

No. You're allowed to do whatever you want with your deck and the order of the cards in your deck as long as you shuttle afterwards.
Okay, let me explain this to you in math terms. We'll call "loving with the starting order" X, "shuffling to be sufficiently random" Y, and "acceptable end state of deck" Z.

If X+Y=Z, and Y must equal Z, then X has to equal 0. Thus, if you remove X it does nothing to the equation (and can stop loving puttering about with your deck). If X has any other value, then Y != Z and you are by definition cheating as you are doing something that has an undue (i.e. any) effect on the final state of your deck, such that it cannot be considered random.

I know it's hard, but you're just going to have to stamp out your insecurities and superstitions about the fickle hand of fate. Yes, you will get mana flooded and mana screwed sometimes because random chance includes that. It is a fact of this uncaring universe. Do whatever you want between rounds; pray to whatever deities you like, have a cigar and a shot of rum, sacrifice a bucket of fried chicken for all I care. But doing anything but shuffling when you should be shuffling is either slow play or cheating and you should avoid both.

I read somewhere that 7 (proper) mash shuffles is statistically enough for sufficient randomization, but that number might have been from someone's rear end just like any other.



Y axis is distance from a perfectly random distribution (1.0 being a stacked deck), X axis is number of shuffles. This is for a 52 card deck but the extra 8 cards in an MTG deck don't matter too much.

I don't know, that graph and math looks pretty subjective to me. Please stick with the facts here.

mcmagic I'm surprised at how dense you're being on the subject of how many shuffles it takes to successfully randomize a deck (and saying it's "subjective" lmao), when it's been brought up in this freaking thread with linked statistical references at least once every few months.

"That must weigh heavily on your soul. Let me purge it for you."
Maaan I should have mana weaved. Went 5/2/1 at Manchester with BW Control. Some high points:

Keeping an opening hand G1 with both my Hallowed Moonlights, then finding I was against Bant Company.
The look on the face of every opponent I cast Reality Smasher against
Getting better against GW tokens and Company because I barely played against any bastard thing else
Thinking I might Day Two when I beat GW Tokens round 8 in 20 minutes

I think I played Bant company 3 times, GW Tokens 4 times and Naya ramp once. Guy I talked to who made day two said he didn't hit any archetype twice.

Had to deal with Evolutionary Leap a couple of times, it suuuuucked. It just let them keep up card advantage, but I was able to keep removing what they played, got really close to winning in spite of it but didn't make it. Missed a Chance to Unmake one in favour of a Nissa and I think it was a mistake.

A player is caught with the best card in his matchup in his lap by a judge. The player says he didn't intend for it to be there but that it fell in his lap during shuffling and he was afraid to say anything. Do you take him at his word and give him a warning?

Rifling is no different than mashing. Both can be done terribly in sleeves and both can be done very well in sleeves. Both depend totally on the condition of the sleeve and the person shuffling. I don't know why this weird debate keeps coming up.

mcmagic posted:

It certainly is because both are major game violations and both players are admitting to knowing that they did them. Asking them to be downgraded to a warning because of "intent" is dumb in both situations.

10+ is good if you're not clumping cards too much, and takes no time at all. No point in not shuffling the deck more. Exactly the same as riffle shuffling.

If you can't riffle shuffle and can't mash shuffle well then either you do the spready-outy-mixy thing on the table for a minute or two or you accept that your shuffling will be poo poo and do the best you can.

The graph that static equilibrium posted seems to indicate you (general you) want to go at least 11, and probably a few more since you probably aren't perfect at mash shuffling.

Really mash shuffling takes so little time that 12-13 of them isn't meaningfully more of a burden than 7.

11 sounds right, sense 7 was the stated number for 52 cards. 8's probably good for limited then.

A single pile shuffle is good sense it lets you count your deck or immediately know if something is up with your deck size. Like for example an opponents card got mixed in with yours, or one of yours with theirs. (everybody has seen this before) Or to make sure you sideboard properly. I've also seen at least one incident where a guy admitted to me that he kept a card of his opponents and knocked it on the ground, so he could call a judge on his opponent at a PTQ a few years back. Of course I could name a billion slimy stuff people have done at PTQs before.

I personally do a single pile shuffle and then mash shuffle until my opponent is done pile shuffling, doing whatever the gently caress. That typically ends up being about 15 to 20 mash shuffles minimum though. If the first pile shuffle comes up weird I will investigate though and repeat the process.

It's the same level of proof required for a civil court case (which ya know this would be if being judged by ya know an actual Judge)

I mean realistically speaking, you can only have really have 5 ways a judge can think about an incident. For sure did it (90+), probably did it (above 50), not sure (exactly 50 very rare they call another judge at this point or give benefit of the doubt), probably not (below 50), and for sure not (below 10).

patriarchy sucks
There are precisely two good reasons to pile shuffle, preferably between rounds:

1) To count your deck. It's a quick way to make sure you've got exactly 60 and didn't drop a card on the floor, or forget an aura, or miscount when sideboarding.

2) To make sure your sleeves aren't physically sticking together.

Anything else is superstition at best and cheating at worst.

By the way the two-sigma or whatever it's called for a 60 card deck is 8 riffle shuffles. If you're 'mash' shuffling correctly it's the same amount of randomization as riffling, so 8 mashes.

Yes because I've had games where I dropped a card on the floor without realizing it or kept one of my opponent's cards by accident or where I accidentally boarded one too many cards in/out and I'd rather not lose a game to something that stupid. it takes 15 seconds.

I do a single pile when I create my deck, because too many times I've miscounted and sleeved up 39 or 41, but I never pile shuffle at a match. Too much risk my opponent will see me do it and it'll trigger their drat minds to pile shuffle a bunch of times.
