Well, what I've learned with power planner loop is, like what quincymccoy said, that some archetypes have a re-enabler.
So I wanted to make a competative Genex deck.
I was wondering about the role Birdman plays in the Genex Archetype. It hit me during the Power Planner loop.
Basicly, you normal summon Power Planner, get Birdman, summon Birdman by returning Power Planner and summon it again if you have Ultimate Offering. The cycle continues.
Most Genex (Ally) monsters, like Power Planner, have an effect that activates when normal summoned. Genex Ally Birdman lets you get one of those monsters back to be normal summoned again and let you have it's effect again.
Using this knowledge, you can try things like making an OTK deck using Brionac and Ultimate Offering or something.
