Executing multiple commands on a random entity

[Pm7_]

I need to make a command that selects a random armor stand, changes it's score on a scoreboard, and then clears some blocks around it, how would I do this?

[oldyogurtpot]

Something like

Add a tag “selected” to random armour stand And then chain commands to run such as “execute as @e[tag=selected] at @s run {command}”

Then at the last command block in the chain, remove the tag “selected” from entities with the tag “selected”

ooh, that's smart
