Rogue has several stats combination Event : Slip Away, Cheap Shot, Breaking and Entering. This is similar to Slip Away except with different stats pair. That's welcomed because now either intellect-leaning or combat-leaning Rogue can get a high accuracy Evade, which is helpful in high player count boss fights or enemies laden with keywords and while-ready effects.

However note that Bum's Rush has 3 effects : exhaust, bonus damage (over success), and push. Slip Away has just 2 effects : exhaust, and long evade (over success). I think in many dicey situations, the "push" in Bum's Rush and "long evade" in Slip Away is the desirable outcome so you don't have to deal with it again too soon. Though both doesn't work with Elite, Bum's Rush "push" is not gated by over-success like Slip Away "long evade", so the spent 2 resources for Bum's Rush is more likely to work without additional commits. You can also push non-Hunter away and stop worrying about it. 1 damage is a nice bonus, and if that brings HP down to nice number and you intended to finish it, you can decide not to push with the "may" clause.

However if you decided to push and they have Hunter, they do get priority attack if they just move in and hit you the next round, unless you move further away or move into it.

Based on the wording of other cards with multiple conditionals, eg Rite of Seeking, the push on Bum Rush appears to be unrelated to if you succeeded the evasion attempt.

That would mean Bum Rush can be used to "permanently" deal with non-hunter non-elite enemies, preferably also non-alert.

This card is nuts, and I don't think people quite understand the sheer power creep it bring for a level zero card (granted, there are leveled up cards that are even more insanely power crept than this, even at Level 0)

At first glance, this can looks as just a slightly more powerful version of Cheap Shot, with the extra bonus of moving an enemy to make up for the fact it can only be used against foes engaged with you.

That is not even half of the story

In the framework of the Rogue cardpool, this being an Evade is a game-changer, as it has more direct synergy with what Rogue likes to do: Evading! This can benefit from both Pickpocketing and String Along at once, in ways cards like Breaking and Entering cannot, and it can get around Retaliate, unlike Cheap Shot which counters Alert. That seems a minor thing, but Retaliate, is much, much more common as a Keyword than Alert (in fact, Alert didn't exist until Forgotten Age) so most of the time, you are going to avoid a painful counterattack in case you auto-fail the skill test

Bum Rush has also much better synergy with certain Investigators than Cheap Shot and Breaking and Entering:

1) Finn can use with his extra action to basically disable an enemy for a turn or more and still do whatever he wants

2) Jenny and especially Preston aren't good evaders by default, but the cards let's them move a non-elite enemy even if they fail the evasion attempt. Look at the wording: it's listed as a separate effect, unlike the evasion and damage being part of the reward for succeeding the skill test. So this basically becomes "spend 2 resources to move a non-elite enemy 1 location away", which against enemies that are not Hunters, Patrollers, Warring or move by any other effect, it's often as good as killing them: the rest is the icing on the cake for them

3) Rita and to a lesser extent Wendy can use this card in combination with Belly of the Beast to gain a clue. Belly of the beast is a crappy event, and this will basically bump the resource cost to 3, but turning an evasion attempt into a clue is often less work Roland has to do fighting an enemy multiple times to defeat it.

4) Combining this with Cheap Shot lets both Michael and Tony have ways to reliably and regularly evade enemies. That opens so many shennanigans with Dirty Fighting for them that Tony couldn't enjoy with Stunning Blow

5) But I think the worst abuser of this is without a doubt this gender fluid bastard: Kymani can use this on their evasion attempt on an exhausted enemy to also add their Combat on top of their Intellect: that already doubles their skill bonus to +4 before addtional modifiers and bonuses. AND deals them one damage, which if it does have the same timing as resolving their reaction ability, can make the test even easier. It's insane the amount of crap Kyman can get rid off with this, even Agent Fletcher eats shit here.

I am probably missing some other very good synergy with some Investigators or cards, but I believe I made my point none the less. I am just glad that FFG decided not to print a Level 2 version of this in the style of Breaking and Entering and Cheap Shot. But if it ever gets made... Oh god.
