CardTamers is a group where you can collect original creatures that are based on plants, breed them, and there are several RP aspects, as well as a host of interesting NPCs and a storyline (in progress).  There is currently an event where you can get rare creatures, too.

This group is looking for admins to play "ArenaMasters" which are similar to Pokemon Gym Leaders.  To be considered, put the name of the character, one of the creature types from the group (found in the journals), and a description or image of the character.

Members are also welcome and join requests are automatically accepted.
