Event Hordes for shiny hunting

[SercaK]

I got on my mind that in holidays like xmas or easter they could add tematic hordes (like delibird or exeggcute) just for a limited time. This would be a great thing for the players that have shiny hunting as focus on game. I know that we are not the most of players but i never saw something like this on pokemmo. 
This would work like community day in pokemon go but without increase the shiny odds just add a limited time horde for more efficient hunting.

I dont know if make this is viable but i'm sure that many people will be happy with.

idk man giving rares hordes could really fk up the economy cuz rng can be really unpredictable, i'd rather have new hordes added with new regions just like they did with sinnoh
