Abundant Bioenergy

Each time you tap a land, gain double the
amount of mana that land tapped for.
Creatures you control gain x +1/+1 counters
where x is the amount of mana Abundant
Bioenergy has produced.
You gain x life at the end of your turn where x is
the amount of used mana Abundant Bioenergy
has produced.
Bioenergy flows through everything, it is the building
blocks of life, and a dangerous weapon if wielded proficiently
