Adventuring Party

Adventuring Party is all colors.
When Adventuring Party enters the battlefield,
put X member counters on it.
When Adventuring Party dies, create X 2/2 blue adventurer creature tokens with "{t}: Add one
mana of any color," where X is the number of
member counters on Adventuring Party.
{t}: Add {u}{u}{u} to your mana pool.
