Alright sorry for the holdup, but based on discussion so far I feel comfortable doing the following things.
Light Screen / Reflect: Fall into a similar mindset of hazards and are totally competitive in nature. People don't want them, so blacklisted.
Poison-type coverage (Sludge Bomb, Sludge Wave, Poison Jab): People seem comfortable saying that at least Poison-type coverage is an unhealthy coverage typing to add to CAP28, as it has a positive matchup against both Kerfluffle and Jumbao quite directly. Steel is regarded as a typing that does similar things but with far more drawbacks in an offensive typing. Blacklisting.
Steel-type coverage (Iron Head, Flash Cannon, Iron Tail): I personally think this is fine, but there are some people who object to both Poison- and Steel-type coverage in thread and I would like to hear their argument fully as to why Steel coverage is unhealthy for CAP28. If those detractors could go in depth in their arguments against it, I think it better help convey the point. Iron Tail is also controversial due to its increased power, so a little more defense towards it being acceptable is necessary. If no opinions change by thread's end, I'll approve these moves.
Pseudo-trapping moves (Infestation, Whirlpool, Sand Tomb) Many seem to think it is a dangerous route to go, and I am inclined to agree. Some say that it does fit with the goal of stop pivots, since the regens can't do so without VoltTurn in this case, but really don't work to disprove the idea that they could have a negative effect. While I totally understand the idea that it fits concept, I would rather err on the side of caution here. Blacklisting.
Entry Hazards (Stealth Rock, Toxic Spikes): I've held off this verdict long enough, but the usual indifference towards them has turned fully into an opinion against them. It's clear we do not want these moves in our repertoire. Blacklisting.
Water-type coverage: Most people seem to see it as an unnecessary coverage type. I am inclined to agree. Blacklisted.
Fairy-type coverage: Same as with Water-type coverage, people see it as unnecessary. Blacklisted.
Everything else not covered I am still deciding on, so I would like some more discussion on those. Specifically I would like some more talk on Acrobatics / Dual Wingbeat, Earth Power, and Wild Charge and how much we need them.
