Conjuro
Exilia todas las criaturas. Incuba X, donde X es la cantidad de criaturas exiliadas de esta manera. (Crea una ficha de Incubadora con X contadores +1/+1 sobre ella y "
: Transforma este artefacto". Se transforma en una criatura artefacto Pirexiano 0/0.)
If Sunfall resolves but doesn’t exile any creatures, you’ll incubate 0, creating an Incubator token but putting no +1/+1 counters on it. It will still have the ability to transform, but you might need to figure out how it’s going to survive first.
