So I've been toying around with putting echo back on the board and I came up with this:

Echo (30)

-stay on target (2)

-intelligence agent (1)

-advanced cloaking device (4)

Season to taste with the rest of the list. I figure when you get in close you never are in arc again. Thoughts?

Stay on target would turn off the acd brother. Go to bed, I'll see ya for pew pew in 15 hours lol

Yes, but if I see your dial, sexy decloak to a prime position, then red my way behind you I'm okay losing the cloak.

You end up predictable the next turn though, and anything turreted takes you on a one way trip to sadtown
