Well, you don't have to do his missions if you don't want, Echo. I'd offer to take yours off your hands, but, not really possible.
Heck, just take advantage of the large number of people flailing away at Freaks missions to snag some easy wins (or at least ties) ... there's not a lot of us Freaks fans out there. The only thing saving us right now is that the ELO bans haven't grabbed the usual suspects (The handful of really GOOD Freaks), so, we have a window.
The Freaks are best played with the poison as a happy bonus, truth be told, rather than a core component. Play as if you have a group with no clan bonus at all, just rely on your abilities, and if poison does a point or two, great! Just don't rely on it.
They don't HAVE to rely on thier bonus but without it thier damage is is limited.
Freaks damage is normally 5 or less. While they do have a few 6s 5 or less is normally what you will have to work with. With no 8s and only three 7 damage cards (one only has 4 power, one has no ability and one is a good damage reducer) Battles can become predictable or rely on you winning 3 rounds or inflicting the poison and waiting while the other clans just smash in a one or two hit KO.
With most Clans needing you to pill 1-2 just to match them, some sealing the bonus or worse the abilitys and others lowering the Freaks main point thier high power or boosting themself higher it ends up as an unfairly uphill battle the whole time.
One of the problems I have with Freaks is that Poison get's more and more useless as the fight progresses. The best situation to illustrate this is say you are on the 4th round and at 4 life, the best you can do is take your oppenent to 5, Well poison doesn't take effect the turn that damage is dealt resulting in a lost. However replace that with say the Berserk Clan and you will bring them down to 3 resulting in a win. Also Poison doesn't stack, so say hitting with Hula doesn't cause double the poison effect. Which is odd since the only use for a Poison ability in a clan that always has a poison bonus would be against SoB clans.
However I don't know if there away to fix this that won't making Freaks totally broken,
