If Nym spends a charge to keep a bomb from exploding that already have a charge on it, does Nym's ability also affect the charge? It seems like player's choice to me as i think the wording for the timing window is the same for both:"when a device would detonate..."

Thoughts?

You could use Nym to prevent the fuse from being removed, yes.

"If there are game effects that share the same timing window as a player’s
ability, the game effect is resolved first." (RR - Ability Queue)

"When a device would detonate, if it is fused, one fuse marker is removed
from that device instead, and that device does not detonate." (RR - Fuse Marker)

I think, the fuse marker is a game effect and is resolved first.

@S4ul0

While you are not wrong about it being a game mechanic, they dont, in fact, share the same timing window.

Nym happens "Before a friendly bomb or mine would detonate"
While a Fuse happens "When a device would detonate" (or during, if you will)

So Nym actually triggers first. As Fuse is a replacement effect. You remove a fuse instead of detonating it, while Nym flat out prevents the detonation in the first place, thus the fuse doesnt have an opportunity to trigger.

I understand. Thank you.

"• Replacement effects are not added to the end of the ability queue as they are resolved at the timing of the effect they are replacing." (RR - Replacement Effects)

i agree with @Lyianx . i would define the fuse as a player effect as well, since it's printed on an upgrade card. it's still a game effect, though. the two terms are not mutually exclusive, mind you. just some game effects are also defined as player effects.

would still be great with a proper definition in the rules reference of what constitutes a player effect.
