You could probably make a shuffler that used suction cups to lift cards from one pile into two or three piles, then back from three piles into one. That way cards would never touch each other except by being stacked which ought to be safe for them, and each iteration would resemble a riffle shuffle. It would be slow as poo poo though and take a jillion sorts to get the top card down towards the bottom.

The suction would be hell on the sleeves and cause repetitive strain to the cards. Why not just hire blind monks to rearrange the cards in accordance with the Bible code?

Hmm...well the FNM shuffle is a difficult technique that differs greatly from the hold-em shuffle and the PTQ shuffle. I'd say it's a 3.5/10

Guys, there's a much easier way. Get a D-X where X is your deck size (probably a D60.) Now arrange your deck in any order. Roll the die. Put the first card from your pile into the position that comes up on the die. Roll the die again. Put the next card into that position, or reroll if the number has already been rolled. Totally randomized, no damage to the cards, and no cheating. It's perfect!

There are some fixes in this week's Magic Online downtime notes.

The cancel button functioning as "OK" cracks me up. How do you gently caress that up?

But I do really hate their system for Convoke and Delve. As soon as a Convoke spell is selected, your creatures get BRIGHT RED BORDERS, and your opponent now knows, "He has a convoke spell in hand he's considering casting." Same goes for Delve, which highlights all graveyard cards. I feel like it's a huge oversight to not make this information only display to the player holding the spell.

Wadjamaloo posted:

This. I had an argument with this old guy who was SO loving SLOW once. He actually tried to say that anything beyond 6 shuffles (he even got the number wrong) UNDOES THE RANDOMIZATION and starts to re-order the deck. My response was essentially, "You keep saying that word "randomization". I don't think it means what you think it means." He was using it the way too many magic players do: as a synonym for "uniform distribution".

He also had to separate the lands and spells in his deck between every game and basically went back to deck building. Then he mana weaved followed by a pile shuffle and two lazy riffles (unsleeved). I called him on it constantly and he hated me for it since in matches against me where I shuffled his deck for him properly he didn't get perfect hands :iiam:

pile shuffles are useful if you're worried about the sleeves sticking together. There's a reason pros do it as well.

On shuffle chat: it does seem like it would be prudent to use 3rd party shufflers for any top 8/featured matchups to prevent the waves of shuffle cheats.

Yeah I don't really believe this either. In a riffle shuffle the card on top will be on top of one of the two piles, and then will end up somewhere near the top of the combined new pile. It seems crazy that 6 repetitions would lead to a uniform distribution of probabilities of final positions for the original top card. Ditto for the bottom card.

I should make a little markhov chain thing with some assumptions about how far individual cards move in a good riffle and see. Hrmmm

I pile shuffle because double sleeved decks are kind of huge (and there's always some try-hard at FNM who bitches about double-sleeves despite Standard Abzan Midrange costing $600 goddamn dollars).

I'll see if I can find the link when I get home, but it was a pretty thorough study that came up with number. IIRC it was talking about poker, but I think it mentioned that deck size doesn't actually change anything, or not significantly.

Many autoshufflers have optical sensors. These would detect foreign cards and have mini shredders that destroy foreign cards and use the waste to print out an application for US citizenship and a coupon for rosetta stone - english.

So for 60 cards, 7 is probably not sufficient. How much more idk, I tried to look into the math and it is way, way, way over my head.

http://www.ams.org/samplings/feature-column/fcarc-shuffle

∥Rk−U∥≤P(T>k)=1−∏j=1n−1(1−j2k). = (DAFUQ???)

Of course a mash isn't a perfect riffle, so I'd guess 8-10 is probably where a magic player should be at for true randomization.

Aha I found a paper that explains it:

http://projecteuclid.org/download/pdf_1/euclid.aoap/1177005705

Say your deck is 20 cards labeled 1 to 20. After one riffle it will be something like


1 2 10 3 11 12 4 13 14 5 6 etc


You have two interleaved sequences of rising cards, 1-10 and 11-20. If you riffle again you have 4 rising sequences, and so on. The number of sequences doubles each riffle and once it outnumbers the number of actual cards in the deck you are halving your 'distance' from a uniform distribution with each additional riffle.

So yeah in a 60 card deck 8-10 riffles ought to do it, assuming they are good riffles.

This is what I do because I'm clumsy and have giant hands. I can mash shuffle an edh deck in my hands without much problem. I mash shuffle a bunch, cut it a few times, and repeat the process a few times. All my decks are double sleeved too so they slide together super smooth and easy.

I generally split my EDH deck into two 50-ish card piles. Riffle shuffle the top halves of both piles together. Repeat for the bottom halves. The two newly shuffled piles become your new 50-ish card piles. Repeat this process 4 - 5 times.

If it is an in-game shuffle, I'll probably just do a quick mash and have my opponents do a multi-layered cut.
