Netcheral, God of Curses

Indestructible
As long as the number of Curses on the battlefield
is less then 7, Netcheral isnt a Creature.
At the beginning of your precombat mainphase,
add one mana of any color to your mana pool for
each Curse you control.
At your end step, gain life equal to the number of Curses on the battlefield, then each opponent
loses life equal to the number of Curses attached
to them.
