Ok. Very confused from the wording of this question.

1. I assume you mean Purgatory Knights Leader, Demios Sword "Chaos Execution!"? If so, you cannot call Demios or Abygale with each other, as Demios requires a Purgatory Knights and Abygale requires a Black Dragon (All Purgatory Knights, to my recollection, are White Dragons).

Unless there's some sort of effect at play here?

2. Demios Chaos Execution is an Impact Monster. Cards do not lose their Card Type, unless stated by an effect (Transform, Ride). Impact Monsters do not inherently lose their Impact Monster Status after they attack. So they remain as Impact Monsters.

You can swing with Demios Chaos Execution, all you want, and activate its effect, all you want, over and over and it will still remain as an Impact Monster.
