I use Phact because he contributes to the system and generates more green orbs. Kaede floods you with heart orbs you don't really need, because her LS requirement needs way more green orbs than heart orbs. I stopped using Verd because of too much trolling (then again I think I was using her on Kali, which isn't always a great idea). Now it's possible to use something like Ishida or Sylvie (on friend lead), with Phact to fix the board if needed. For Beel, it's possible to get by with WeeJas + Phact + Kaede. Though if you meet him after Lifive, it's usually GG. So yeah it's not an airtight team but it works well enough for me. Now that UU Vishnu is out, I have actually been thinking of replacing Phact with him, and maybe inheriting something like... Phact or Verd on top. But I'm not sure I want to give up the haste for his skyfall active. He brings two more fingers and more SBR, and has way better stats, so it might be something to try out. I think putting Perseus on him isn't a bad idea at all. Depends on what your other subs are... basically just put your spike on the sub whose active you need to use the least.
