Telosian Cyberman

{2}: Telosian Cyberman deals 2 damage to any
target. Activate this ability only once each turn.
Whenever Telosian Cyberman blocks or
becomes blocked by a non-Wall creature, you
may pay {2} and prevent all combat damage
Telosian Cyberman would deal this turn. If you
do, gain control of target creature blocking or
blocked by Telosian Cyberman. It becomes a
copy of Telosian Cyberman.
