Here's the seed: 812014930105396964

In my hunt to find the "perfect" seed for a server I'm starting up for my friends, I spend about 3 hours searching through over 9,000 known quad witch hut seeds for seeds that have all rare biomes near spawn, using a super sophisticated method know as actually looking at every single seed image.

Just a note: by 3500 blocks from spawn I mean the actual distance when traveling diagonally, so in actuality I am taking about -2500, -2500 to 2500, 2500.

I used /u/puppynosee's list of 16,000 quad witch hut seeds to get me started:

Here's the image of the super seed

And a link to mineatlas of seed

Within this 5,000 x 5,000 block area (2,500 blocks from 0,0 in all directions) you can get the Adventuring Time achievement.

Some other notable things about this seed:

• There is a quad slime chunk very close to the quad witch huts around (-760, 1200) (mineatlas link) and there are at least a couple of other quad slime chunks within 2500 blocks of spawn

• You spawn in a Mega Taiga

• Two mooshroom islands within 2500 blocks of spawn.

• Unusually large Mesa biome

• Mesa Bryce (2400, 1912)

• Savannah M (500,2200)

• Sunflower plains north of spawn

• Flower Forest (-400,1500), also near a sunflower plains

As far as I can tell, the only overworld biomes NOT within 2500 blocks of 0,0 are Mega Spruce Taiga, Redwood Taiga Hills, Mesa Plateau F M, and Jungle M (although there is a Jungle M just 500 blocks further (2450,3024)).
