i have to add, i really feel i need vogoth. just not certain, as im basically f2p.

Wukong is a solid option, especially if you already have a high tier soul for him.  He won't help much in regular CB but you don't look like you should be struggling there with your champs.

King Gallcobar, Umbral or Husk would be decent Hydra options if you wanna progress there.  Not much of a fan of Vogoth myself but he could at least supply Leech for your CB team.

Judging by who you actually are showing, I daresay Hydra should not be in your consideration list at all. Sure, throw whoever you have at it, but you really shouldn't be building champs specifically for it.

As for CB, you've got quite a bit to work with. I think your best bet would to build a standard 1:1 comp with everyone between 170 and 189 spd, around something like:

• Skullcrusher (slowest)
• Giscard (second slowest)
• Kreela
• Ghrush (turn off A2 and A3)
• Orn

You're going to struggle due to no debuff removal, but you should be able to get enough damage out of it anyway. Ideally have Kreela or Orn take the stun, by making them lead on Red/Blue affinity respectively. On Green affinity just cry, throw a tantrum, and come back tomorrow.
