The blitter was about as advanced as a 2D graphics device needed to be,
with up to three block sources per operation and a variety of methods of
combining the three. It could also draw patterened lines. All stuff
you'd expect to see in a modern 2D VGA card.

True, but the copper could trigger the blitter to do memory
manipulation.
