Actually the biggest problems I had in testing it was against Nightmare/Piranas. Without their bonus their damage is generally lacking quite a bit. And SoA weakens them more than i thought, as their bonus is only usefull one time. But yeah right now I guess I'm playing pretty predictable.
One thing Freaks need imho is a good damage reducer, maybe a protect:bonus with good stats and maybe a useful sob or +life card. I think they lack cards to support their poison ability in a way Jungo and Sakrohm support Sylth and Sigma.
Butterfly Circus (ELO) I did this preset a while ago... and Eklore actually has sinergy with Freaks... because most opponents will try to get to 5 pillz in the first 2 rounds, so that should give you a good advantage, plus eklore's damage are algo helpful and 2 dmg reducers that are Wolfgang and Spiaghi to prevent getting so much dmg
putting in Spiaghi and Uranus as substitute reducers works well too =) just remeber that the strategy usually isn't KOing the opponet, but instead beating cards that would deal high damage. Poisons gonna sink in then sooner or later and the DRs can keep u above 3 live.
You can easily put 8 pills into Baldovino at the first round. Even if ur opponet doesnt counter with any pills at all, if poison gets through and u got a bunch of reducers in ur hand, u have pretty good chance to win. Let life gainers get through, they usually just make poison do even more damage.
"do Freaks actually stand a chance and if not what would they need to become elo competitive"
In the Elo metagame, almost certainly not.
The very fact that they're almost never seen in Elo as a mono, and, in my experience, never above 1250e or so.
Honestly, their bonus just doesn't stand up in the context of modern UR, and I don't see how anything but imba OP abilities could give them the needed buff for a competitive chance in higher tier Elo.
