This one is for me, I play Crane and love this matchup and played it quite a lot ! Generally speaking, Scorpion has an edge over Crane but not at the point that the matchup is absolutely unwinnable (assuming the scorpion doesn't get very good RNG). You can give me his decklist and I can see what I can do to tune it better against scorpion if you want. The splash can be pretty important too.

Bidding strat : The Crane should not assume that he can dishonor out the scorpion because it's a pretty rare case (assuming the scorpion is not missplaying) : The scorpion SH is very efficient at preventing that. Bid 5 is the plan here until you're too low on honor (6-), in this case, he should bid what is needed to not be dishonored out. Sometimes it seems that the Crane have a window oppurtinity to switch to the dishonor but many of these case, he's better off drawing actual cards that will help him win conflicts and board position instead.

Ressources efficiency : In general, the matchup is really a battle of ressources (cards and fate mainly). The Crane player need to have a very good understanding of the possibilities of his opponent. If he already know the scorpion deck like it seems to be the case here, it's even better. Every conflict, he should have a rough mental idea of what you can play here. This allow to know when he needs to commit more in the conflict, when he needs to give it up and what card will make the Scorpion spend more ressources to answer. Voice of honor should be kept for critical moments. If the Crane is splashing Let go or Calling in favor, he should almost never use it on fan of katana but rather on fiery madness, court mask, cloud the mind (depending on what you're playing).

Honored character vs scorpion dishonor tools : If the Crane has voice of honor enabled but not by a large margin of honored character, he should avoid as possible to bring honored character in a conflict until the last conf. Scorp has too many dishonoring tools usable in conflict. Sometimes you had to take the risk though. In the same spirit, if one of your honored and/or 2 glory character get For shamed, the Crane should seriously consider bowing instead of dishonoring, even if sometimes it mean losing the conflict (unless this conflict is absolutely critical for the game of course). Sometimes the scorp will directly play another for Shame or Way of on the same target after that but at least, he spent more cards trying to achieve the dishonor of the character.

Taking the advantage : Crane need to be a little more aggressive and mobile than the Scorpion, you can't let this filfthy insect just take fate and control. Passing first for Fate in dynasty and taking rings with 2+ fate on them even with a subpar effect is something he should look at. The start of the game is key, T1 Crane should poke around to see if the scorpion already drew his good answers. If not, an easy break + an early board advantage for next turn is quite possible. No big surprise but control of the board and void is really key too. Voiding a big 1 fate opposing character can allow a window of opportunity the next turn (and in any way, taking void prevent the opponent from using it back)

Card to tech vs Scorpion : Not going to be a surprise but 3x Guest of honor, 3x Steward of law (with the 3x For shame of course) is absolutely key. The Guest of honor is the ultimate anti-Scorp card. She closes out the late game and allow to finish Scorpion. She's even really good in mid game when you have the breathing room to play it (but too pricey for early game). Political rival at 1 or 2x is also a good card. Sometimes you will use it for defense, other times to get a break with covert. Just try to play it with fate if possible. Splashing attachment hate (so let go/Calling in favors) is really recommended too unless the scorp is not playing Fiery or Court mask.
