Ruling Aerodactyl disk...

*Hopes that this is the right place to ask this* If it isn't then, I'm really sorry.

Hi!

I have an Aerodactyl disk that I got free inside a packet of Quavers crisps years ago, and I think that I read somewhere that you can use it in the Pokemon TCG game, so I was wondering, can you use this Aerodactyl disk in the Pokemon TCG game and if you can then, what can it used for in the Pokemon TCG games please?

Here is a photo of the front and back of the Aerodactyl disk:

That is a Pokemon Coin. You can use it for randomizing. Aerodactylo side is heads, the other side is tails.
edit:Only coins from EX-Ruby and Sapphire on are considered legal randomizers. Credit to Hypno68 for catching that.~Mark
