Please don't forget to agree on a set of Tiers or any other type of battling guidelines before battling someone to avoid accusations of "Cheating".

Our own GTS tiers can be found here:

Users are not required to use our tiers, but it is in the interest for both parties to agree on a set of rules whether it's ours or made up on the spot before the battle occurs.
