Remove the ink cartriges for ammo and put them to the side. Next, tape 2 of the empty pens together and put the 3rd on top like a T shape. Next, bend a paper clip at a 90 degree angle at the center and tape it by the corners on the T shape.

Cut a rubber band and cut 2 pen caps in half . Tie both ends of the rubber band on the 2 pen caps and insert both of the caps onto the single pen shell. Then, tape the binder clip anywhere you like on the 2 pen shells. The farther back you put it, the farther it will fire. Then, cut the pokemon card to about 3/4 normal size and cut a hole in that for the ballista to fire . Then, put the rest of the pen cap just behind the pokemon card to improve accuracy.

Take the ink cartriges and slice a little slit in them in the back for the rubber band to grip. Then, you can load and fire to get your space back!
