This is just a simple game like Maxedge's Make an Attack. You just have to use your imaginations and make your items.
Let me start first.
Sitrus Juice
Its an item which heals the user's Pokemon by half.

So thats how you make it.

By the way, I don't know what this [PLAY] means. I just used it to make the game more attractive.

Fire Bone.
Cubone's upgraded bone after burning.It also burns the foe by contacts.
