Unlimited Possibilities

Until end of turn, each mana ability you control
adds two more mana that ability would produce,
tapping a permanent to activate a mana ability
deals 1 damage to you.
At the beginning of your end step, you lose 1
life for each unspent mana on your mana pool.
"I wasn't high, wasn't wired, just clear. I knew what
I needed to do, and how to do it" -Eddie Morra
