Pyroar > magmortar > charizard > busken.
If anything I suggest Busken drops to B+ or A-, despite knowing how well it does with speed boost, I hate using it for sheer unreliability and it has competition for physical sweeper with zard.
Zard / pyroar / magmortar all offer an amazing set in special attacker, but pyroar being immune to shadow ball is a huge niche right now whilst being a lot faster than most of the tier is hella nice. However,if when sceptile gets banned, magmortar will be more openly available to check things since lilligant will go back to being number 1 choice for offensive grass type. Zard is simply my third choice due to its need for a lot of team support, but by definition zard falls under S rank as it has multiple extremely viable sets with a huge amount of coverage options that it just leaves all 3 equally viable in some form or another, depending on what your teams needs exclusively.
if anything, I'd suggest Pyroar + mag stay a+ / move to S at some point after sceptile ban, Zard probably to A despite having niche and busken to A- if this is the case. However, I can also see reason why all 4 of those pokemon are A+, since they all carry a viable niche in what they can provide to a team, none being identical, and i think the second the suspect test is over, it may become easier to define where each fire type's ideal place in the VR rank is.
