Even experienced builders fail to trigger the achievement due to subtle mechanics.
Do not trust an untested trap! Lure a passive mob (like a cow or sheep) onto the pressure plates.
When the mob steps on the plate, the redstone signal will travel to the pistons. They will simultaneously shoot out, crushing the mob upward into your lava or cactus. The moment the mob dies from this piston-initiated encounter, the achievement prompt should pop up on your screen.
Skeletons shoot arrows, so you need a design that breaks line-of-sight. lovely craft piston trap achievement guide top

Top tip: Use a repeater set to 2 ticks to delay the piston until the skeleton is exactly in the kill zone.
If you tell me the exact game and whether the achievement requires a player kill, mob kill, or immobilization, I’ll give a tailored blueprint with exact wiring/tick values. Even experienced builders fail to trigger the achievement
Here’s a clean, easy-to-follow text guide for the Lovely Craft (Piston Trap) achievement in Top (assuming you mean Top as in Top Heroes, Top War, or a similar mobile/builder game — if not, this still works for any piston trap achievement).
In Lovely Craft, the Piston Trap Achievement (internally coded as achievement.piston_kill) requires the player to kill a hostile mob solely via piston push damage or suffocation—not with a sword, bow, or lava. The kill credit must go to the piston’s movement. The most common method is pushing a block into a mob’s hitbox, or pushing the mob into a solid wall.
Why is it tricky? Pistons do not deal direct damage. You must exploit environmental damage (suffocation, crushing, or void drop) with the piston as the final "weapon." Achievement Flag Fail: Some versions of the game
If you simply crush a mob between two pistons, they might just get pushed out of the way or take minimal suffocation damage. To guarantee a kill, place a cactus block or a block of lava directly above where the two piston heads will meet. When the pistons extend, they will push the target up into the lethal element.
Find a flat area and dig a trench that is 2 blocks long, 1 block wide, and 2 blocks deep.
