The Dark Lord, Sauron

When Sauron enters the battlefield create artifact
The One Ring. Sauron may be attacked directly
He can't attack, block or be buffed, and doesn't
heal during endstep. If Sauron would take
damage you may prevent any or all of the damage
and spread it amongst creatures in your control.
If Sauron's on the battlefield during your endstep
you may place a +1/+1 token on all other Red and
Black creatures you control. If Sauron leaves the battlefield, all creatures with these tokens on lose
them and take
