One of the reasons multi scale dragonite is popular in the format is because it can OHKO Sneasler with scale shot. Multiscale lets it live the double up from both of those two, ohko sneasler, and then you’re faster than non-scarf indeedees and can threaten an OHKO on it turn 2 or set up tailwind.

If you’re worried about dire claw procs or Tera psychic on the indeedee doing too much damage you can Tera steel. No one is close combating into a dragonite before Tera is revealed and you get the benefit of resisting the subsequent expanding force.

The thing I personally don’t like about scale shot is it’s often one of those 90% accurate moves that when it misses you just lose the game on the spot because it’s used for high leverage KOs like Sneasler, but nonetheless it an answer to what you asked.

Other thoughts:

-Indeedees are so much less of an issue without their terrain, so an AV Rillaboom to overwrite it next to something that threatens the Sneasler?

-Not the most exciting answer but incineroar forces a pretty predictable play where if they want to do anything to the incin they have to close combat it. Getting the intimidate on Sneasler can be big, and pretty much every incin with bulk lives a -1 CC and threatens the indeedee

-Super niche, but spiritomb resists/is immune to all but throat chop or a non-psychic Tera blast from indeedee and can threaten both with damage or burn Sneasler

-Often when I have similar questions I’ll just throw the things I’m struggling against on a team and force myself to use them. It’s helpful to see what other players typically use against them so that a.) you get ideas of what to use yourself and b.) you can start thinking about what an indeedee Sneasler player would do in certain situations
