Random Graveyard Effects - Acceptable Use in Eternal

[MaximumCDawg]

So, there are at least two Innistrad cards that choose a card from the graveyard at random.  For example, this:

Charmbreaker Devils

Creature - Devil   
At the beginning of your upkeep, return an instant or sorcery card at random from your graveyard to your hand.
Whenever you cast an instant or sorcery spell, Charmbreaker Devils gets +4/+0 until end of turn
Illus. Dan Scott   4/4

Given that the order of the graveyard matters in eternal (I gots to cast muh Spinning Darkness), how on earth do you work these cards?  Just hope you have a die with exactly as many sides as there are random options in your yard?  Write down the order and put them back after shuffling and selected at random?  Just figure it out when it comes up?

If there are n eligible cards in the graveyard, get the smallest die available with >=n faces.  On a roll of i from 1 to n, pick the ith eligible card from the top.  Otherwise, reroll until you roll 1-n.  Anyone who plays one of these cards can pick up a 20 sided die which should generally be sufficient.

Any method that allows for each card to have an equal chance is acceptable.  Physically shuffling the cards is only one such method, and there's no reason that can't be used if the players can track and ensure the cards will return to the same positions in the graveyard after (assuming it's a format where graveyard order must be maintained).  Elric's method also seems acceptable and doesn't require physically removing all the cards from the graveyard.  I'm sure two players in a game where this came up could likely come up with multiple other agreeable methods should the situation require them.

Shuffling could lead to clerical errors resulting in an incorrect gamestate.  Rolling a die can work if you don't mind counting, but who carries a die around all the time?  I just spread out the cards evenly, making sure to maintain graveyard order.  I then close my eyes, and throw a lawn dart up in the air.  Repeat until one of the cards is hit, or my opponent is slain.

So the players just "figure it out" when the situation comes up?  That seems confusing.  Plus, what happens when you have a full yard and Charmbreaker Devils in play?  How on earth is that game not going to go to time if one player insists on recording, shuffling, and reordering the graveyard every upkeep?  Could you be sanctioned for slow play based on your choice of how to deal with the random graveyard effect?

Yes the players figure it out.  As with various other parts of the game that require a random determination, there's no one set way it must be done.  The players can use any mutually agreeable method.  One player does not get to decide unilaterally what method is used.  If the players cannot agree on something, they can always seek the intervention of a judge to help them.  There is not, nor is there likely ever going to be, a single official method for selecting a random card out of your graveyard while maintaining the order.

If you are making a conscious decision to use a needlessly slow method of resolving game mechanic, I can't imagine any reason why you shouldn't get an infraction.

I really don't see why you're making such a big deal out of this. It's the exact same things as if an opponent was being unreasonable about any other aspect of the game typically left to personal preference. You call a judge to make them stop being an idiot.
