Re: Nightfall...
Bahamut with nightfall has the potential to be a major threat to two of the game's most popular team archetypes: foresight taunt pewg lightning and jihadi scythe.
Scythe is obvious and has nothing to do with weather; he is ghost.
Foresight taunt pewg has everything to do with weather. Foresight is useless in night and if he mistakenly tries he loses a turn. Lightning as normally ur fastest element get pushed to the back of the attack stack as your slowest attack now which can have advantages. Also, if ur worried about rain it is simple to maintain the weather in this case. Pewg being slower than bahamut if they both cast weather on same turn during night, pewg rain would resolve first where night would then most likely follow after keeping the weather nighttime.
