At the beginning of your upkeep, you may choose
target non-enchantment, non-planeswalker
permanent. If that permanent is a creature, the
creature gains defender or trample until the
beginning of your next turn. If the permanent
is an artifact, you gain control of it until the
beginning of the next end step. If the
permanent is a land, put a stamp counter on
it. Lands with stamp counters adds one
mana of any type it could produce.
