What to know about this week

Here's what jumps out to me in the days ahead:

Many new debuts

There are a whopping six* debuts this week:

Dynamax Magikarp (Monday, during Max Monday)
Arrokuda, Barraskewda, and Cramorant (Tuesday, during the Ultra Unlock: Water Festival)
Shiny Lunala (during the Wednesday raid refresh)
Mega Starmie (during Saturday's Super Mega Raid Day)

* Seven, if you want to include Dynamax Gyarados

Arrokuda, evolution Barraskewda, and Cramorant are the big draw on Tuesday. None of these will appear in the wild, with Arrokuda featuring in Field Research, the 'Water Festival' Go Pass, and from Rainy Lure Modules.

Cramorant, meanwhile, will be found in Eggs, the 'Water Festival' Go Pass, and Go Battle League rewards. Cramorant has several forms where it's gulping down other Pokémon (including poor old Pikachu) which occur during battle, meaning there's just one variant to actually catch.

In terms of getting everything else that's new, it's what you'd expect from their respective events. And remember, if you want an easier way to encounter Lunala en masse for the shiny, it'll appear during the Wednesday night raid hour.

Is Mega Starmie any good?

Legends: Z-A's best new Mega - a Starmie that sprouts a pair of legs - debuts in Pokémon Go on Saturday (11am to 5pm), but it's unfortunately not really up to snuff. It's in DialgaDex's B-tier list of Water-type attackers, and though it fares much better as a Psychic-type in the S-tier, that's a packed field, ranking 28th overall (or 11th if you discount other Megas such as Mega Mewtwo, and Shadows).

So it's decent, but nothing to worry about competitively. That said, I'll be wanting one ASAP so it can stomp around as my Buddy on the map screen.
