I thought about this card a lot. Eventually, I have my doubts but find it got way more dirt here than deserved.
My main problem is that you have to use for the evade. Because to play this card effectively you need a high skill value, but if you have high you usually just fight the enemy. I think for this card to be less niche using should be optional (which would also be more flavorful IMO).
That said, now for the good part - the forced effect: "After attached enemy moves: Exhaust it." You know when enemies move? When they hunt! But okay, we already got that covered here and that's probably the main selling point of this card. But after they hunt you and exhaust you are engaged with them, so you still have a problem to deal with next round. Meh.
Or do you... ?
See, whenever you move enemies engaged with you also move. That changes a whole lot regarding the utility of this card, since it opens up synergies with cards that let you move without spending an action! Say hello to:
- Safeguard (0)/(2)
- Cat Burglar
- Shortcut (0)/(2)
- Elusive
- Think on Your Feet (0)/(2)
PathfinderToo bad.- Warning Shot I find that synergy surprisingly good, if it fits your deck's playstyle.
- Pendant of the Queen
- Heroic Rescue (2)
- Righteous Hunt If you pick the Bolas-ed enemy up on the way to the target - quite situational.
- Flute of the Outer Gods
- Fang of Tyr'thrha Also needs another enemy as target, but can be played while engaged with your Bolas-ed one.
- Hiking Boots
- Join the Caravan
- Archive of Conduits Comparable to Cat Burglar in the way it interacts with Bolas.
- Prophesiae Profana
- The Red Clock (2)/(5)
- Cyclopean Hammer Theoretically yes, but if you play this OP card why use Bolas?
- Gené Beauregard Can help if you move into the Bolas-ed enemy's location.
- Grappling Hook
- Summoned Servitor with Wings of Night.
- Power Word
- Predator or Prey
- Task Force If another investigator plays it and targets you.
- Misdirection
- Bum's Rush Even if you fail!
- Doppelgänger
- Bound for the Horizon
- Dakota Garofalo
- Ancient Stone
- Nimble
- Pete's Guitar
- Shroud of Shadows (0)/(4) If you find a curse.
- Trench Armor
As you can see, some playstyles also incentivize having an enemy with you.
Let me think what you know ;)
