Curious, can the interdictor title untap Aresko to use him twice, or is it limited to upgrades only?

You can use it on Aresko. He's an upgrade.

Here's the fun thing about Armada...

If its a card attached to a ship, and its not a Damage Card... Its an Upgrade Card.

Slot is irrelevant.

Even no slot is irrelevant.... That Admiral you took? The one you have to have as your Force Commander? Totally an Upgrade Card.

Nice. I thought so, but sometimes wording is so technical.

Side note (that's been covered elsewhere)- exhausted cards mean nothing - except you can't exhaust an already exhausted card.

So while you can MS-1 ion cannon your opponent's admiral, they can still use the agility.

Ms-1s are really only good for ECMs or another interdictor

and probably some more that I've missed...

"ECMs and Another Interdictor" only account for 4/16, or exactly one quarter of the Upgrades that MS-1s are Potentially useful against...

Hitting an Intel Officer it Wulff could be ready good.

Ok I stand corrected, but it is a niche upgrade. Considering all the other crit upgrades, plus likelihood of landing a crit on a specific ship, with one specific upgrade. Though not knocking them, I've enjoyed tossing them around a few fleets.

Compared to many of the blue crit upgrades? It's pretty good.

And if you can't use it, you still have the default available.

And its also the Cheapest Non-Default Critical Effect available in the game.
