I believe being immune to Toxic is the most important status for CAP29 to be immune to, especially as a bulky setup sweeper. While having an immunity for only when we switch in may seem like a marginal benefit, it actually is extremely beneficial to the strategy CAP29 would use. You see, if we switch into Toxic and we are immune to it, they have to attack us to change our type before being able to Toxic us. Not only is this an ideal opportunity to set up, but it also could potentially drain the opponent's momentum in trying to be able to neuter CAP29. Depending on our coverage the actual Pokemon trying to poison us, we could also be able to force out whatever tried poisoning us as well.a) How much value does a Toxic immunity offer in the context of a bulky setup sweeper?
While this does deal small chip damage to us over time, the only reason I see us wanting to be immune to Burn is if we wish to choose a physically oriented type combination. Being immune to Burn requires being a Fire-type, and while being immune to Toxic does require being Poison or Steel, I feel that prioritizing Toxic makes more sense when, if we end up being a special attacker, Burn will be rather insignificant to our strategy.b) How much value does a Burn immunity offer in the context of a bulky setup sweeper?
I feel that while there is some usefulness in being immune to Paralysis if we wish to increase our speed, I feel an immunity to Paralysis should be our lowest priority. As a bulky set up sweeper, while we may not have rock bottom speed in the end, speed is arguably not our most important stat. As such, I feel an immunity to Paralysis is just not something to focus on.c) How much value does a Paralysis immunity offer in the context of a bulky setup sweeper?
