Stamp Transparent () 
stamp transparent ()::pen
Category Pen
Type Stack
Introduced in 2.0 prealpha
Removed in 2.0 alpha
Stamps with transparency values 20, 50, 80 (top row, left to right) and unaltered (bottom)

The stamp transparent () block was a pen block and a stack block. The block stamped an image of itself onto the stage, similar to the Stamp block, but with a partially transparent value depending on the block's input.

This block was only available in the 2.0 prealpha from Scratch Day 2011. It was removed to minimize the number of blocks and its functionality being included in the Stamp block using the amount of the ghost graphic effect for the sprite.[1]

Workaround

This block can be replicated by using the ghost effect: 

set [ghost v] effect to (. . .::grey)
stamp
set [ghost v] effect to (0)
