How do you get ace in dinosaur king

You get Ace the same way you get Chomp but you have to be Rex in order to get Ace. If you are Max than you will get Chomp. First you have to beat the game to unlock the stone circle. Then go to Europe and go south. Turn right and go down until you can't go down anymore. Then turn left and you will see all the elements as stones all around what looks like a big, skinny rock. Run on the stones to enter a code. The code to get Ace/Chomp is: Lightning, Grass, Fire, Earth, Water, Water, Lightning, Fire. Once you do that you will appear in the middle. The big, skinny looking rock will blink and then the words "the seal on the ancient shrine has been broken." will appear. After that happens go across the little bridge that is on the left. Then go down and you should see a little dirt ramp. Go on the ramp and go right. There should be a building that looks kind of like a steel house with open doors. Go in there. Once inside run to the middle. There should be a closed treasure box. Once you open the box you will receive your card. If you are Max you will receive Chomp. If you are Rex you will receive Ace. After you leave the Shrine (steel building/house) it will lock again and the doors will appear closed. When this happens you will have to go back to the stone circle and enter another code to unlock it again and get a different card.
