Hired Claw’s activated ability cares whether an opponent lost life this turn, not how their life total changed. For example, an opponent who gained 2 life and lost 1 life in the same turn still lost life.
Whenever you attack with one or more Lizards, this creature deals 1 damage to target opponent.
: Put a +1/+1 counter on this creature. Activate only if an opponent lost life this turn and only once each turn.
