Enraged farm

my picture is what a modular dark room looks like

Would my design work?

it would, but it would not be very effective

Hmmmm, so it just wouldnt spawn that much

If you just wondering ...it is of course possible

ver. 1

ver. 2

Dont' look here...

Pretty useless for now...
and that was so long ago....

Is that a private farm?

yes.

I think the spawning conditions for enraged mobs are basically the same as regular ones. Enraged mobs have more health, though, and are immune to lava/fire.
So basically, you should be able to just make a regular black box mob farm, then kill all the regular mobs with a height drop or with lava (lava may be better because it lets your sword do a higher percentage of damage to the enraged mobs). Then hack away at the enraged mobs with a looting 3 sword.
Makes sense in theory, anyway.

I was going to go with some kind of machine using pistons and lava since (to the best of my knowledge) netherhounds are the only mobs able to spawn in lava.

i dont think they spawn in lava....they have a large sight range tho and swim up from it or jump down from the nether-roof

How come you always see them in the middle of lava lakes when theres no spawning areas above them that they could have fallen into.

an "enraged farm" or an "enraged mob farm"?

i may be wrong, but ive noticed they spawn in caves under the lava and swim up, or spawn in little outcroppings way up on the nether roof and jump off
