MTG Salvation

Besides mill being what seems the main strategy for b/u what is a good type of deck with these colors?

I always wondered who the dimir would rely on as a ally

Everytime i try to login i get a "your login to magic has failed please try again"
Ive done all trouble shooting and called them and nothing still.
Does anyone know how to fix this.
Ive never had a problem till now

I was wondering which guilds would ally itself with one another if needed?

And also which shards and clans would team up with one another?

Is this place all artificial?
Like most of the other shards look more natural especially if you compare it to naya or bant or something.
Whats the whole story behind it?

it doesnt have to be tribal hydra was planning on using other creatures in general. wanted to know which hydra to go with out of the ones listed

id like to make a hydra deck but not sure if i should go with r/g or g/w
and for either deck what cards should i go with?

i have
plant hydra
apocalypse hydra
heroes bane
hydra broodmaster-love this card
kalonian hydra
miscutter hydra

my plan was if i was told g/w it be a +1 counter deck while if it was r/g it be aggressive

i dont have to use all of them its just what i have

what type of creatures of they?
are they mechanical or supposed to organic
