Let's talk guardian deities based on their types and abilities

Tapu Fini
>immune to all status on the switchin
>everyone is immune to status for five turns
>everyone resists dragon for five turns
fucking busted, rip stall

Tapu Lele
>psychic terrain sounds like a powerful effect
>probably doesn't threaten powerful priority users anyway though, sd talonflame flare blitz, sd pinsir return, huge power azumarill play rough...
>forces m-sciz to uturn out I guess
>psychic moves get 50%(?) boost
need more info, but psychic terrain sounds like a powerful support option for glass cannon sweepers, especially psychic types like alakazam

Tapu Koko
>literally only prevents sleep
>garbage version of misty terrain except:
>electric moves get 50% boost
if it has good offensive stats/moves to leverage the electric boost it could be okay, but as a whole this field effect is fucking trash compared to the first two

Tapu Bulu
>field effect is literally leftovers for everyone on the ground
>grass moves get 50% boost
>earthquake is weaker
boosting grass moves is not so great, might be good for a ground weak team I guess but levitate and flying spam is all the rage anyway, big fat meh imo
