Im not going to comment much on your hyperbolic statements of its desirability and rarity

Once Superfactorial resolves and you've summoned Laplacian succesfully, effect window pops up asking you to activate Laplacian's on-summon effect to detatch and send cards to GY (if there are other trigger effects activating at the same time and they decide to activate them, priority will be given to the turn player) - if you intend on using the negate effect provided by Diameter to respond to an opponent's effect that has priority over yours on Laplacian's summon, you'll have to "skip" the on-summon effect to send cards to have the option to negate

A good utility card

These sleeves are also incredible value, with a bundle of 1000 costing around $14/11
