This is important because the whole point of Ultra Polymerization is that it lets you use the same set of monsters for two different Summons in the same turn
Your spells, such as Allure of Darkness and Chaos Space , allow all your Light and Dark monsters to get banished, thus triggering their own effects
But like others have said, persistence and dedication are requisite

However if you have to play Gurdurr in the active Pokemon spot I would use Will-O-Wisp every turn except for the turn before you want to evolve Lampent into Chandelure, I would use whichever move you can afford to use, I would use Strength if you only have two energy cards on Gurdurr and Pummel if you have three energy cards on it
Whenever a Gate you control enters, you may put this card from your graveyard on top of your library
