They can, max is 3. You can add the type orbs in the middle, all 9 are shown at the top, or just leave a blank circles and tell me the types and I can add them. You can look at my previous ones to see what they look like.
IF YOU WANT, YOU CAN DRAW ERETHORBS FOR MY GAME, JUST MAKE SURE THEY LOOK LIKE THE OTHERS, WITH THE WISPY GHOST TAIL AND THE TYPE ORB IN THE MIDDLE. YOU CAN LEAVE AN EMPTY CIRCLE FOR THE ORB AND I CAN PUT IT ON AS LONG AS YOU SAY THE TYPE. ALSO PUT THE NAME.
