Nathanial, Malicious Ward

Shadow
Nathanial enters the battlefield under the control
of an opponent of your choice.
At the beginning of your end step, put two +1/+1
counters on Nathaniel. Then, Nathaniel's owner
and controller may draw a card or create
two Treasure tokens.
{b/r}: Put a -1/-1 counter on Nathaniel and goad
him. Nathaniel's owner loses life equal to its
power. Only Nathaniel's owner may activate
this ability.
