CD Factory

A CD Factory is a custom stage built to gain Stickers and, of course, CDs. The "Factory" can literally be any custom stage, but most formats require conveyor belts to be a success. A CD Factory allows one to quickly collect Stickers and CDs by abusing conveyor belts, and Sandbag's ability to give out rares (stickers and CDs). It works because if Sandbag is the only item enabled, the only items it can drop are Stickers and CDs (Which cannot be toggled via the item switch)

How to make it
There are many ways to make a CD Factory. Here is one way:
 * 1) Enter Stage Builder, and ensure that you have the conveyor belt stage piece (Edit Parts B, create 5 stages).
 * 2) Create a small stage and two large sized conveyor belts down starting from the bottom right side, and the second connected to it in the middle right. Build a medium sized block at the bottom left of the map so that the bottom is completely covered.
 * 3) Build a large conveyor belt two spaces above the medium sized block, and reverse its direction. Test out the level, and make sure that all of the conveyor belts lead inward, and don't push you off the stage.

Then, play on this stage, and turn every item off except for the Sandbag. Use a character with a strong, spammable A combo like Kirby or Ike, and proceed to hit the Sandbags as they come to you. Pick up any dropped stickers and CDs, but be quick with CDs, as they disappear quickly. In addition to these, there are a lot of other ways to make a Factory. Keep in mind that you will have to hit the Sandbag hard and quickly for this to work. Also keep in mind to limit your treasure hunting, as the Sticker counter will reset after an as-of-now unknown limit (presumably 99) leaving you with none of the stickers you toiled to obtain.

However, this design is relatively inconvenient for one player to use, in that ungatherable stickers and CDs may fall on the extra block. The small size also limits the available surface area for item spawning. The most efficient Sticker Factory to date is created as follows:
 * 1) Use the largest available custom stage template.
 * 2) About halfway up the available space, create a line of conveyor belts, all leading into the center. You will have to alter the size of some of them to get maximum horizontal space, but it's best to use as many of the very large size conveyors as you can.
 * 3) Directly above the center of the conveyor belts, to which all things on the map should be pulled, place another large conveyor belt. Its direction is irrelevant, since either side of the main platform rolls things to the center.
 * 4) Below one of the sides of the main conveying platform, place several ladder pieces that are easily accessible from the main stage area.
 * 5) Turn all items off except Sandbag, and turn the frequency to High.
 * 6) Enter Special Brawl. Turn the speed to Fast and the gravity to Heavy.
 * 7) Make P1 a character with a fast, spammable, vertical-knockback up tilt. Mario is a viable choice.[[image:AdCDFactory.jpg|thumb|right|High efficiency CD Factory]]
 * 8) Make P2 a floaty character that can easily reach the ladder under the stage.
 * 9) When the match begins, move P2 to the ladder, out of the way. This stowage area keeps him/her from getting beat up while P1 gathers stickers and CDs, but doesn't create a needless block that wastes an item spawn point.
 * 10) Let P1 get pulled to the center. As Sandbags are pulled toward him, use his up tilt to repeatedly hammer them, stopping only to gather the fallen items.
 * 11) The conveyor directly above the center keeps the sandbags from flying up too high, allowing you to continually pummel them without wasting time. Any items that spawn on top of it are pulled off onto the main platform, then pulled directly to P1
 * 12) The high gravity makes the bags and items fall faster, so they can be hit more often for more reward. The high speed simply improves the overall time-efficiency of the system.
 * 13) Extra vertically-placed conveyors are a possibility, but if it takes too long for the spawned items to reach P1, they may disappear before they can be collected. This is especially true of CDs.
