I've been wondering recently, is Jirachi is a good candidate for S-rank?
S Rank: Reserved for Pokemon who can sweep or wall significant portions of the metagame with little support, and Pokemon who can support other Pokemon with very little opportunity cost ("free turns"). Also the home of Pokemon who can easily perform multiple roles effectively, increasing their versatility and unpredictability. If the Pokemon in this rank have any flaws, those flaws are thoroughly mitigated by their substantial strengths. If there are suspects, they will come from this rank.
Jirachi is one of the most versatile pokemon in the tier. His analysis pretty much speaks for itself due to having a whopping 7 sets, all of them very good.
He's incredible at filling a lot of roles on a team such as:
- Stealth Rocker
- Sweeper (both physical and special)
- Scarfer/Revenge Killer
- WishPasser
- Wall
- Excruciatingly annoying paralysis supporter
And probably even more roles that I didn't mention.
- As a Stealth Rocker, he sets himself apart from the pack due to keeping momentum (U-turn), and also having the ability to completely ruin the opponent's Stealth Rocker by flinching them to death. Not to mention that fast, frail hazard setting leads run a big risk if they try going toe-to-toe with him, because on the off-chance that it's a Choice Scarf lead and not a Stealth Rocker, Iron Head will ruin them.
- While Jirachi isn't usually physically sweeping, he does have great coverage and the ability to flinch past all of his counters as a nice perk.
- The special sweeper is often found on Rain teams, and it's excruciatingly difficult to kill when it effectively only has one weakness and a buttload of resistances. Not to mention, just like the physical attacking variants of Jirachi, this one can easily hax its way through its counters with Thunder paralysis, and even Water Pulse confusion.
- The Choice Scarfer is a dangerous revenge-killer due to its great coverage and flinching ability with Iron Head. He's also a very good Choice Scarfer due to an SR resist, access to U-turn, and numerous resistances to get in safely.
- Jirachi is a great WishPasser, because not only does he pass a decent 202 HP, but he's able to come in and do it over and over again, while sustaining himself by taking advantage of his own Wishes. Because a lot of opponents get paralyzed by Jirachi as well, there are a lot of times where he can even get the WishPass off untouched.
- I'm going to put the last two points into one, because they go hand in hand. Jirachi loves to paralyze opponents with his annoying Body Slam and Thunder Wave. He's also ridiculously hard to kill because of a number of factors including Wish, his typing, great defenses, and numerous flinches. Being ParaFlinched is possibly one of the most annoying things, and because of how difficult it can be to kill Jirachi, he can do it over and over again.
And one last point is that a lot of supporting pokemon hate having a Choice Scarf Tricked onto them. Jirachi, however, doesn't care. If it has Iron Head, all Tricking a Scarf onto it does is just give it more things to flinch to death.
Basically, Jirachi is an amazing pokemon who can perform damn near any role on a team, and because of Serene Grace and an awesome movepool to take advantage of it, he's able to muscle past a lot of counters. This is why I think Jirachi should be S-rank instead of A-rank.
