Creature - Human Soldier 2/2, 2W (3) First strike {1}{W}: Tap target creature blocking Master of Arms. Prevent all combat damage that creature would deal this turn.1 "Being the best usually means proving it to everyone." -Gerrard of the Weatherlight
Illus. Dan Frazier
5/1/2007: Remember that normally, tapped blockers still deal and receive damage in combat. Master of Arms prevents the damage that the targeted creature would deal, but the creature will still receive combat damage.
4/1/2008: Master of Arms has received errata so that its functionality is much closer to how it worked at the time it was printed. (When _Weatherlight_ was released, tapped blockers didn’t deal combat damage.)
