Pixie Factory

When Pixie Factory enters the battlefield, create
a 1/1 blue Fearie creature token with flying.
{2}{t}, tap any number of Faeries and/or Elves:
for every creature tapped this way, create either
a Clue token, a Treasure token, a Food token
or an Acid token.
{3}{t}: create a 1/1 green and black elf token.
..where the magic happens.
