I want to teleport a player to a location relative to another. For example, I might want to teleport Steve so that he's exactly 50 blocks on top of Joe.
I can't use /tp, since that will teleport Steve directly onto Joe's location. Is there a way I can teleport someone to somebody else's location, but with an offset? I'd like to do this with a single command, if possible.
This was a very interesting challenge for me to work out. There are many parts to this problem, which are a lot harder to accomplish than one might think. There's identifying the player with the status effect, and identifying a set of random players who are not them (since /tp Unionhawk Unionhawk is a valid result of /tp @p @r, and does nothing).
But, finally, here is my setup, which works for a bounded number of players on a server. Some of its flaws include only allowing one game to be played on a given server, and using experience level to identify players. As such, /gamerule doMobLoot false must be used, and /gamerule commandBlockOutput false is strongly advised.
So there's quite a lot of things going on here, as you can see. But this is all accomplished using 4 commands and a hopper clock.
The Group 1 command blocks are there to detect when a player has the specified potion effect, remove it, and proceed to the matching Group 2 command block. I used /effect @p[c=n] 4 0 for that one, which removes the mining fatigue effect from player n on the server (going down the list of players on the server). When that command evaluates, the Group 2 command blocks give that player one level of experience using /xp 1L @p[c=n].
From there, the next time the hopper clock pulses, the "Group" 3 (you only need one) command block teleports a player with 1 level or more to a random player without any levels using /tp @p[lm=1] @r[l=0]. When this command evaluates, the "Group" 4 command block clears the experience level of all players using /xp -9999L @a.
There is no way to make it with one command, but you can achieve it with 5.
/clone ~ ~ ~ ~25 ~5 ~25 ~ 200 ~ filtered force minecraft:stone
/fill ~ 200 ~ ~5 225 ~5 minecraft:grass 0 replace minecraft:stone
/clone ~ ~ ~ ~25 ~5 ~25 ~ 199 ~ filtered force minecraft:stone
/clone ~ 200 ~ ~25 225 ~25 ~ ~1 ~ filtered force minecraft:grass
/fill ~ 200 ~ ~25 225 ~25 air
It will create a copy of stone in sky, check for having air to place a block, an then return blocks and clear the sky.

The
/tpcommand accepts relative arguments (~), but you won't be able to do it in a single command. You may wish to use a pair of command blocks to execute them quickly and more or less seamlessly.The following will teleport Steve to Joe, then zero blocks forward (in the x direction), fifty blocks up (in the y direction), and zero blocks to the side (in the z direction).
The format is as follows:
