"contriver" - Translation from English to Arabic

We shall find in him a shrewd contriver, and, you know, his means, if he improve them, may well stretch so far as to annoy us all, which to prevent, let Antony and Caesar fall together.
يجب أن ندبر له حيلة بارعة فكما تعلمون، إذا استخدم وسائله وقام بتطويرها، ربما يتوسع كثيراً ليزعجناً جميعاً

It's the er... air of contriver, as I don't care for.
أنها مخترعة اله جويه على ما أعتقد
