Docent of Perfection

If you control three or more Wizards while you control Docent of Perfection, it won’t transform yet. It only transforms while its triggered ability is resolving after you cast an instant or sorcery spell.

Docent of Perfection’s triggered ability resolves before the spell that caused it to trigger.

For more information on double-faced cards, see the Shadows over Innistrad mechanics article (http://magic.wizards.com/en/articles/archive/feature/shadows-over-innistrad-mechanics).

Final Iteration’s triggered ability resolves before the spell that caused it to trigger.

When Docent of Perfection transforms into Final Iteration, the instant or sorcery spell that’s on the stack doesn’t cause Final Iteration’s triggered ability to trigger.

All Wizards you control get +2/+1 and have flying, not just those created by Docent of Perfection or Final Iteration.
