Bombs, arrows, fireballs... Plenty of people 'create' items. But I agree, this is a much more passive one which seems pretty ugh.
How many people have seen the two IGN gameplay videos? You see character selection with changing colors, stages, and like a 2 minute battle between Metaknight, Diddy kong, Mario, and Yoshi. It's really cool, and Metaknight looks so badass. Diddy looks fun too, and FLUDD looks cool to mess around with.
EDIT: yeah and 'intros' are confirmed so
