Boost

Kicker {1}{g}
When Boost enters the battlefield, search your
library for up to two basic land cards, reveal
those cards, put one onto the battlefield tapped
and the other into your hand, then shuffle.
If Boost was kicked, whenever you tap a land for
mana, add one mana of that color. At the
beginning of each opponents precombat main
phase, that player adds one mana of any color
of their choice.
