Is the position of the lever (visible at lower right) fixed?
It looks like you want the L&R pistons to retract, then the T&B pistons to extend for one state, with the return being the T&B pistons retracting, then the L&R pistons extending (ie. an ABBA sequence). Is this correct?
How much of the ground level/floor cannot be gone below? [Assuming the two levels under the shifting 2x2 area are hopper mine carts above hoppers, where so the hopper lines run?]
What constraints (if any) are there to running RS above and to the four sides of the 2x2 shifting floor?
From where (and at what level) do you access the kuill chamber in manual kill mode? (Is there a manual kill mode?)

No, the lever position is not fixed but I'd like to have it nearby.
That's exactly the case.
The hopper line will probably run straight in any direction, i don't know which atm but i don't really care either.
Other than that, there are no obstacles.
I guess you mean Redstone (RS?). There are no constraints, except the hollow 4x4 tower going up to where the mobs spawn.
As for the last question I actually don't have an answer right now, but I want a manual kill mode with the bricks and auto kill mode with magma blocks.
Do you want the floor to be able to open both, or is it just either/or? If only either/or, then I'd just make 4 magma blocks, then on top of those have the moveable regular blocks. No need to move the magma blocks in that case.
But if you want to be able to open both and make a hole, I attached a circuit that will work. You MUST use a non-moveable blocks like bedrock and a beacon. The beacon (or similar) must be used so the redstone doesn't activate the pistons that the torch is controlling (beacons work like non-moveable half slabs). The observers update the pistons next to the bedrock since they will activate 1 tick before the torch ones and get stuck otherwise.
EDIT: Forgot to add the open floor/closed floor toggle line. This essentially turns the observers off so the bedrock piston don't get updated and stay retracted. The only issue is you have to toggle the main switch after changing the open/magma switch.
This is far from pretty, but will work the pistons to swap the floor with an input signal (eg lever) powering either of the green wool blocks.
(The glass in the tube is just for visibility; the S-piston and RS-block activator is just so I could watch the pistons while using the lever.)
[The brick slabs in the orange wool RS line are necessary if the repeater is set for 1 or 2 ticks, but not if at 3 or 4.
Using full blocks in these positions with the repeater @ 1 or 2 causes the upper pistons to remain extended despite having no source of power: I cannot explain this behavior other than being due to random RS bugginess (the fixing of which I wish MS/Mj would prioritize adding over new bells & whistles & gongs & chimes… )]
There are problems, however…
If one leaves the rails under the hopper minecarts, they are high enough to prevent blocks from being pushed into the space above. (Test rig is in the left hand side of the upper picture.)
If one removes the rails, the hopper minecarts sit just low enough not to pull items through a full block above. (Test is in the bottom of the lower picture, with a block floating above the magenta wool demonstrating the failure mode.)
There is also the issue that the above design has pistons on all four sides of the kill chamber, leaving no direction from which it can be accessed for a manual kill mode.
Suggested 'fix':
Remove the rails under the minecarts and use downward facing pistons to push the magma blocks into the minecart spaces. (It is necessary to do this as pairs of diagonals, and to use pistons to push the side blocks into place after breaking the rail beneath the minecarts.)
Use S-pistons on the sides only (the magenta wool RS line in the above, eliminating the orange line and the top & bottom S-pist n sets), that move bottom slabs into place for a manual kill mode. (These pistons are not strictly needed as magma blocks damage mobs slowly enough that the bottom slabs will merely allow you to let groups accumulate.)
Use of (stationary) bottom slabs in the spaces next to the moving bottom slabs is strongly recommended if the farm can generate 1-high mobs.
This solution allows enough space to stand (on the top of the hoppers), but requires moving at least the center of the base of the magenta wool RS line up by one. (The side S-pistons could also be controlled directly by the lever rather than through RS-torches, allowing a somewhat more compact build. )

As for the first Solution.. How are you able to put Redstone on Beacons? Shift-Rightclick doesn't work for me. So I really couldn't test it. And what blocks are those with 2 arrows pointing right? Observers?
The second Solution keeps destroying itself because in my Singleplayer Test World. It's basically the same i built at first but the Problem occured, that with only one repeater the Sticky Pistons with Magma blocks are just always one tick later. Or do I really miss something here?
It would be the best if either of you could join my Server or something because it would be way easier than to explain with Pictures alone. If you want of course.
Okay my bad, the dust on the beacon only works prior to 1.13. You can use a hopper instead (I forgot those can't be pushed either). And yes the blocks with the arrow are observers (forgot to remove my texture pack before uploading).
Another tip is to place the magma/floor blocks last, cause things will be jumping around while you build it. And as for the other design, use bedrock behind your pistons so it can't break.
The other design could still break as there are Torches right behind the Pistons, not an immovable object unfortunately. Guess you'd have to do it with your little Hopper trick as well.
But one more Question eL_T.. Why do you use Bedrock instead of Obsdian? ^^ It's way easier to get, isn't it? I really don't wanna cheat in that Server and I just tested it.. Working great! Thank you so much for the simple, fast design!
Sorry again, I just use bedrock cause I didn't think about Survival aspects. Obsidian would be the correct choice for sure. I don't even know if you can obtain bedrock in survival. I'm a noob in survival concepts, but am good at building redstone stuff. Glad it helped though!
Hey,
I guess I could need some help with my Mob Farm...
I need this little construction to change the floor with only 1 Lever but it keeps destroying itself the way i build it.
Unfortunately my redstone is really rusty after 3 years as it seems.
Edit: Can't go below Ground Level because there are Minecarts with Hoppers for the Drops.
Version is 1.13.2
Thanks in advance,
Vasho
I’ll help you make it better I am great at red stone so inv me
