Does it say anywhere in the rules that a ship can't be equipped with two of the same EPT? Imagine Tycho with two PTLs... Or two Outmaneuvers.

As long as the card is not marked with the "limited" key word I don't see why not. Thoug PTL has the "once per round" wording so I don't see any benefit in that case.

You would be hard pressed to use the good EPT's like these as they usually have limiters, like no stress to use.

No ship currently has 2 EPT slots.

Rebel Aces introduces A-wing Test Pilot which allows a second EPT. But it explicitly forbids 2 of the same EPT. So you can't equip 2 of the same EPT anywhere.

A-Wing Test Pilot (unreleased)
Rebel Aces Expansion Pack

Your upgrade bar gains 1 {EPT} upgrade icon.

You cannot equip 2 of the same {EPT} Upgrade cards. You cannot equip this if your pilot skill value is "1" or lower.

Incorrect. In the Slave I expansion scenario Preystalker, the bounty ship gets an extra EPT slot without the "no doubles" restriction present on A-wing Test Pilot. There are not many EPTs that can benefit from doubling in any event. Anything that uses an action can only be used once; others do not have an effect that can be doubled (like Determination). Double Push the Limit would not work because it generates a stress, which prevents further actions. Even if you managed to ditch that stress and get another free action, PtL specifically states "once per round."

The only ones that could be doubled are Adrenaline Rush, Veteran Instincts, Decoy, Swarm Tactics, Wingman, Outmaneuver and Predator.

Meh - scenarios don't count.

As far as rules possibilities, they sure do. Make a Test Pilot Green Squadron your bounty ship and carry three EPTs!

Double Push the Limit would not work because it generates a stress

Tycho don't care 'bout yo stress.

No reason duplicate EPTs would be handled any differently from other duplicate cards such as crew. We have rules for them, should be just fine.

Double Push the Limit would not work because it generates a stress

Tycho don't care 'bout yo stress.

Point. He still does not get around "once per round" however.

Could you use dual predator cards to get 2 re-rolls for anyone PS 3 or higher, and up to 4 re-rolls for anyone PS 2 or lower?

Would be pretty sweet on a firespray for that scenario you're talking about.

Would work fine, with the usual caveats about not rerolling a die more than once.

Exactly. At that point it's basically a target lock.
