Ruling Coin flips vs. dice rolls

[God7Fish]

Now I've noticed for some reason people like to use dice during the game, even the new elite trainers box comes with dice. But the cards clearly state "flip a coin" for different purposes. I was wondering if during a tournament if my opponent is required to flip a coin of any reason and he or she chooses to roll a dice...can I insist that they flip a coin? If so do I have to say that before the game starts or each time a coin needs to be flipped?

Now your probably going to ask me why I think there is a difference between rolling a dice and flipping a coin, the probability is that same. Well I've come to notice that most people are really bad at flipping coins and that most likely where the dice thing came from. So I figure I would try and get every advantage I can.

Dice may be used as randomizers, provided they meet the following criteria:

~It's 6 sided, translucent or transparent, with rounded corners (and opposite sides have to add up to 7 as always).
~All the sides need to be labeled with pips, not the numbers 1-6. A logo may replace either the 1 or the 6. Edit: Hold on. I messed up; the dice can use numbers instead of pips, but they still have to be aligned in the usual way a 6-sided die would.
~Even numbers are treated as heads. Odd numbers are treated as tails.
~They need to look noticeably different than any dice being used as damage counters or poison/burn markers.

There is a huge difference between rolling a die and flipping a coin. Coins are more likely to fall off the table and to damage cards.

If the person is using a legal randomizer, die or otherwise...no you may not. If there's doubt to the legality of a randomizer, the head judge has the final say. You may call a judge over and ask if a randomizer is legal, but do that repeatedly and they're going to get extremely annoyed with you.
