SCP 096 The Shy Guy

Defender, Haste, Shroud
{g}: If SCP 096 has a witness counter on it,
remove it. Otherwise, put a witness counter on
SCP 096.
While SCP 096 has a witness counter on it, it
loses Defender, has to attack each combat if able,
and gains +6/+0, First Strike and Deathtouch.
{2}{b}, {t}: Put a witness counter on target creature
you don't control. That creature has to block
SCP 096 this turn, and can block even
while tapped. Untap SCP 096.
