Q: If "Macro Cosmos" is faceup on the field, and my opponent summons a monster, can I activate "Dark Renewal", and will it summon a DARK Spellcaster?
A: You can activate "Dark Renewal" since the condition is met and the monsters will be banished, butsince they were not sent to the GY, the A requirements in this 'A then B' effect in not met, so the DARK Spellcaster will not be summoned.
