Face-Off and Overcome

Play this if your vanguard is "Archangel of Twin Wings, Alestiel"! Choose one of your units being attacked, and it gets [Power] +5000 until end of that battle for each of your rear-guards with odd grades. Until end of turn, when your unit with an even grade is retired from (RC) or (GC), you may put that card into your soul instead of drop.
