RE: What tools in PTCG are used for?
I don't know what other "fancy tools" people use other then Dice, I guess there's sleeves, too. Dice are generally used because they're easier to carry around then those tiny damage counters, and they can also be used as coins because it's easier then flipping a coin, and coins have annoying rulings sometimes. Sleeves protect the cards. I would definitely recommend both of them if you want to get into the game. If you know of any other "fancy tools" that I just forgot about, I'd be glad to tell you what they're for.
