Mix and Mega council has decided to suspect Terastallization!
Terastallization has long been a controversial phenomenon in Mix and Mega. Early in the metagame it contributed to the excessive brokeness of Koraidon and Miraidon, undeniably hastening their bans, and even after they left remained a potent threat on the likes of Palafin and Iron Bundle. In essence, it allows a Pokemon to change up their type, either gaining a boost to their attacks if they chose one of their previous stabs or changing up their type chart and boosting coverage if they chose a new one. Up until recently, however, it was constrained to a handful of Pokemon by the fact that it was incompatible with Mega Evolution, and thus largely only utilized by pokemon that could not make use of that instead. With the new item introductions to Mix and Mega, however, this changed. Prior to its ban, Terastallization helped render Rusted Sword users even more difficult to defensively or offensively answer, and while the introduction of Red Orb significantly suffocates pre-change Tera staples like Palafin, the ability of Rusted Shield users to Terastallize is still something of an issue. Between Rusted Shield and Terastallization, it is relatively easy for bulky setup users like Volcarona and Garganacl to safely gain boosts to potentially sweep opposing teams.
However, that's not to say that it is undeniably overwhelming in its power. While useful, the stat boosts from Rusted Shield are significantly less than that of a mega stone, and Dauntless Shield is admittedly a decent ability but is unexceptional in a metagame full of equal or better options. Which pokemon will run a Rusted Shield and Terastallize is usually obvious at team preview, and always apparent the moment it switches into battle. Rusted Shield sweeps are significantly harder to pull off if they don't succeed the first time the user comes into the battle thanks to Dauntless Shield being a one time effect, and Mix and Mega has traditionally had no shortage of options to force switches from the opposing team. Finally, since Rusted Shield does not boost a pokemon's offensive capabilities, defensive cores have a significantly easier time dealing with their damage output than even normal items combined with Terastallization, to say nothing of Mega Stones; Chien Pao, for instance, is barely stronger after a Rusted Shield Swords Dance than its older Life Orb Terastal set is unboosted, and is slower to boot.
Is Terastallization too much for the Mix and Mega Metagame, or is the phenomenon fine and any issues - if they do rise to that level - more the fault of individual abusers such as Volcarona, or Rusted Shield itself?
Requirements:
Requirements can be achieved by getting 80 GXE with 30 games, down to 76 GXE with 50 games on the Mix and Mega ladder. In order to participate in the suspect, you must create a fresh alt (creation date no earlier than 20 March 2023) with the prefix MNMTR at the start of the name. When you have obtained the reqs, make sure to post proof of your alt's record (generally a screenshot) in this thread, and if you wish to do so, you can also share your thoughts on the test here.
Voting:
Once the suspect period is over, everyone who has obtained reqs will be tagged. The post will then outline a process of blind voting, which will be clarified once the time arrives. For now, follow the above "Requirements" subheading to ensure that you have posted your reqs correctly. You must post on this thread in order to be tagged in the voting thread, however you do not need to include your vote on this thread.
A super-majority of 60% ban votes is required to prevent pokemon from Terastallizing in Mix and Mega.
TL;DR:
- Terastallization is permitted on pokemon with Rusted Shield or no Mega Stone on the Mix and Mega ladder for the duration of the suspect test
- The GXE requirement is 80 and the minimum game count is 30, down to a minimum of 76 after 50 games
- You must ladder on a newly-created alt using the prefix MNMTR
- You must post your reqs in this thread, though the voting process will happen in a separate thread. You are not required to state your vote in this thread.
- The suspect test will conclude at 11:59pm GMT -4 (EST) on Monday, April 3rd.
- A ban vote of 60% is required to prevent pokemon from Terastallizing in Mix and Mega.
