Mega Rayquaza 4-Person Raid Guide

If you're bringing a Mega Evolution to the is fight, then this is generally the one to go with. With superior DPS and a lone weakness to Ancient Power, this is a great option for getting ahead of the clock and scoring some huge gashes in Mega Rayquaza's HP bar, especially if your raid partner is doubled-up with their own Mega Glalie or a Shadow Mamoswine at the same time.

While not quite up to Mega Glalie's power, Mega Abomasnow can hit all of the same major milestones, and is a perfectly viable option. In fact, it tends to have stronger TDO performance against Dragon movesets due to its higher natural bulk... though not by a whole lot. And it also has a weakness to Flying moves, so it can be riskier than Mega Glalie in general.

The one thing that can overtake Mega Rayquaza's double-weakness is none other than Mega Rayquaza. The one true Dragon King, this monster will tear up opposing Mega Rayquaza with its own sheer power, though it's also going to drop fairly quickly for the same reasons. While it can keep up with the Ice Type Mega Evolutions, the down-side to Mega Rayquaza is that it boost Dragon Types while on the field, which are substantially less useful than Ice Types in most scenarios for this raid.

The prime TDO-Mega for this raid, Mega Diancie. It may not have quite the TDO of Mega Aggron or Mega Tyranitar, but it keeps high enough DPS to still be worth considering in its own right. It has the advantages of resisting Flying Type and double-resisting Dragon Type movesets, and it also boosts two of the types that Mega Rayquaza is weak to; Fairy and Rock. However, since these types are not Ice, they will tend to fall behind by comparison. 

Honestly, Mega Salamence can't compete with the above Mega Evolutions even in Windy weather. Its main utility has to be if you're working with a low-level raid group that has a lot of Dragons in their team. But even then, it's largely a sub-optimal pick for this raid.

Same story as Mega Salemence, really.

The lone monarch of this raid, Shadow Mamoswine stares down Mega Rayquaza defiantly. As the undisputed Ice Type King, it's no wonder why Mamoswine takes our #1 spot here. Nothing else in the game can quite keep up with it currently, and its TDO is relatively good as an added bonus. This is definitely the top priority for this raid!

The ever-popular, universal-utility Ice Type, Mamoswine is the starting point for a Rayquaza raid for most players, and that logic extends perfectly to Mega Raquaza as well. Bring all of the Mamoswine that you can, as you're going to need them!

Shadow Weavile has performance similar to Shadow Mamoswine, but a bit lower on DPS and a fair bit weaker in terms of longevity. Still, it's another genuine priority!

The strongest non-Shadow/Mega counter in terms of DPS, Galarian Darmanitan is definitely another top pick for this raid.

No STAB/Super Effective Fast Move? No Problem! Once again, Shadow Mewtwo breaks its way into a raid guide by virtue of its coverage moves, and it's a great all-around pick for this raid.

Alongside Mamoswine, this is the budget-option. Eevee has traditionally been a really common Pokemon for the most part, so scoring a few Glaceon is an easy fix for a lot of players, and it works extremely well against Mega Rayquaza overall.

Weavile's performance falls a bit when compared to its Shadow forme, but it's still a very viable though frail option for this raid.

An oddball on this guide to be sure, Avalugg can actually holds its own with its great Ice Type moveset and solid bulk.

Not as great as its Shadow forme, but still very worthwhile.

Having a double Ice weakness brings out some strange counters, doesn't it? Well, the classic Mystic avatar bird's evil form actually has solid overall performance... just so long as Mega Rayquaza isn't packing Ancient Power.

Didn't I just mention strange counters? Of all of the Dragons in the game, Kyurem leads the pack when it comes to Mega Rayquaza raids thanks to the sheer power of Glaciate. Just... don't expect it to stay for very long.

The dethroned king of Dragons.... but not really worthwhile here. As with the other dragons, Shadow Salamence is actually a sub-optimal counter to Mega Rayquaza due to its relative frailty and lack of double-weakness exploitation. Still, it's solid in Windy weather and/or with a Dragon Type Mega Evolution on the field.

Same story as Shadow Salamence, but a bit less DPS/a bit more TDO.

Rhyperior may not be an Ice Type, but its Rock Type moveset still does solid damage while its natural bulk and resistance to Flying Type movesets makes it a good way to shore up some TDO.

Despite sporting a comparatively abysmal Attack stat, Shadow Regice is a perfect example of just how devastating a 2x weakness can be, as it's still a solid option. Just... please don't raise a Shadow Regice just for this raid, as this may be the only Legendary raid where it's considered "good".

Abomasnow no like Flying moves. Abomasnow no last long. Abomasnow hit hard.

Jynx actually rivals Shadow Salamence in this raid... and that's not really an enviable position considering how badly outclassed it is by the Ice Type titans. It won't last long, but it'll put in some solid DPS.
