Lang, Generous Alpha

Whenever a creature you control attacks, if it has power, toughness, or mana value equal to 1, it
gets +3/+3 and gains trample and double strike
until end of turn.
Whenever Lang attacks, tap up to one target
creature defending player controls, and up to one target creature must block this turn if able.
