It's not certain whether Succubus will work... If they are four times weaker than the target stack, they won't be able to take control of it. It seems that the strength is calculated based on the value listed at the bottom of the creature table in the fan-made guide. However, according to the calculations, it turns out that to control 1 Twilight Dragon, you need slightly more than 1 Succubus (for 1 turn). Twilight Dragons and Phantom Dragons, as is known, cannot be controlled. For Emerald Dragons, you need 1.38 Succubi, and for Green Dragons, 0.98... Hmm... To be honest, I'm surprised by the calculations; the numbers are very modest. In this way, you can control 5 Green Dragons with 5 Succubi in 1 turn. It should be checked.
