Penlington, of the Old Guard

First Strike, Deathtouch
Whenever a creature you controls blocks or is
blocked it gains first strike until end of turn if a creature in combat with it has first strike. The
same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink, menace,
reach,
skulk, trample, and vigilance.
All creatures must block if able, you control your opponents during their blocking phase.
