Primary "role"
This first sentence of the strategy bothers me:
- Bandit’s primary role is to add Gold to your engine after you are successfully drawing your deck.
I think the primary role is to add Gold. Full stop.
A statement about its primary role should not be restricted to when building an "engine" or "after you are successfully drawing your deck". There are many kingdoms where this card will be present, it's infeasible to create such a deck, but it is still a strong card compared to the others.
I suggest rewording it to:
- Bandit’s primary role is to add Gold to your deck. This can be especially useful when at the point of building an engine and you are successfully drawing your deck.
We considered the Bandit-in-non-engine in drafting, and basically found that it's pretty horrible in non-engine cases (and therefore not a "strong card compared to others"). For evidence I think we pointed to Bandit's high skiprate (>60%), poor simulation results in money strats, and low regard in card-glicko.
So while I disagree with your reasoning, your edit's fine and does read more clearly. I'd change it slightly to: Bandit’s primary role is to add Gold to your deck. This is often useful after you've built an engine and you are successfully drawing your deck.
 Reveal/Discard effects not mentioned
The paragraph on the attack capability of Bandit is minimal, only discussing its trashing effect. What about the effects of revealing & discarding opponents' decks' top two cards? I tried to write a sentence about that to conclude the paragraph, but had trouble finding the right words because I'm not sure if those two effects are "rarely" useful ("rarely" used in paragraph's first sentence).
- undo setup of an opponent's next turn, or cause them to not see a good card for a while if the deck is large
- cause opponents deck to flip (which can be devastating in a Counting House combo)
- trigger a discard benefit for the opponent (e.g. Tunnel)
Revealing can benefit the opponent specifically Patron--I think that's the only one.
Should any of this be mentioned in the strategy?
Already discussed in duplicate discussion on Discord, but no, discarding/revealing is on average a wash and just free cycling. the cases where you get bandit matters for this effect (e.g. disrupting NW/CH) are so edge-case-y and rare that they really don't warrant mention in this format.
