Criatura artefacto — Constructo pirexiano
3 / 2
Cuando la Construcción ambulante entre al campo de batalla, puedes pagar 2 vidas. Cuando lo hagas, la criatura objetivo obtiene -1/-1 hasta el final del turno.
You don't choose a target for Ambulatory Edifice's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you pay 2 life this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
