Chapter 2 review
The Polished Cane allows Rogues to attack with a boost from their (typically strong) stat. Note this is still a Combat test so you need to commit or icons to these (and not icons). As you can evade the enemy with an over-success of 2, in some ways this allows you to target the weaker of an enemy's fight or evade value to exhaust them (either with an attack from the Cane, or a conventional evade action).
An unsung beneficial feature of the Cane is pinning Elusive enemies if you manage to trigger the auto-evade. "Succeed by" is checked during the test, while Elusive triggers after an attack resolves and only if the enemy is ready (which they no longer are). Chapter 2 seems to be leaning into Elusive being a common feature on enemies (especially in the Children of Blood campaign) and so the Polished Cane can be extremely useful in these situations.
In terms of how you want to use this, it's a nice means for Trish to kill Black Chamber Operative in a single card. You can lean into combat more with any Rogue if pairing to M1903 Hammerless (scoring the evade and damage with the Cane, and then continuing to shoot them with your gun) - and with André specifically this triggers your additional action allowing up to 7 damage in a turn (almost Guardian levels of damage, and with the enemy exhausted). While Rogues won't often want to run dual weapons, Prestidigitation makes it very easy to flit between Thieves' Kit and weapons on the fly - so it's not necessarily an either/or situation.
Overall I think the Cane is very good. The fact that it test is a necessary balancing feature, as most Rogues typically won't want to run many cards with combat icons in their decks (unless we get a high Rogue at some point in the future for Chapter 2).
