What would happen to the meta Dialga, Palkia, and Giratina get signature Z-moves in a potential DP remake, which activate the Room effects? They fit quite well thematically- especially Inverse or Wonder for Giratina and Trick for either D or P
Well, I’m fairly confident the ubers meta can withstand damn near anything you throw at it, and a Z-move is a fairly costly thing to give a Pokémon, since the Z-crystal expends your item slot – especially considering that Dialga, Palkia and Giratina all have fairly powerful signature items (their respective Orbs) that they might prefer to use (unless they break the rules of Z-moves, the way Rayquaza breaks the rules of mega evolution, which doesn’t seem implausible – if they get signature Z-moves, the Orbs might enable them). Besides, auto-Magic Room and auto-Wonder Room don’t strike me as particularly game-breaking effects. Auto-Trick Room, maybe, especially if you give it to Dialga, who’s one of the slower uber-tier Pokémon (not that that’s saying much) – but then, if this hypothetical Z-move also forces Dialga to give up a move slot to Roar of Time, which seems likely, maybe that’s balance enough.
