I can build you the pet of your choice. Either just train it up and you can skill it, or a fully trained skilled pet.
I pride myself in only using the highest stat spawns for any of my pets. Ready for 120 scrolls and min-maxed stats.
I'd recommend a nightmare for the reason that you get the magery for free, if you want it to dump mana into whomever you PVP.
A cu can also build things like that but it'll be different. Most would agree that CU's arent as good for PVP as nightmares, while you can still do spawns with nightmares just lacking the healing skill.
