{w}{u}{b}{r}{g}: Create five 1/1 Agent creature
tokens with "When this creature enters the battlefield, choose two colors. This creature is
those colors," and "When this creature dies,
search your library for a land that only generates
mana matching both of this creatures colors and
put it on the battlefield tapped. If you control 10
or more Gates, instead search your library for a
land and put it on the battlefield untapped."
