Abundant Nexus

Lands you control produce an extra 3 mana of
any color when tapped for mana.
At the end of your turn, draw 6 cards and gain 6
Life. Put a nexus counter on Abundant Nexus.
If at any time Abundant Nexus has 2 or more
nexus counters on it, you lose the game.
Those who wield its power cannot be stopped, and
neither can that power itself...
