Peeping Tom and Destroyer are currently pretty useless.

Destroyer has the worst cost/benefit ratio of the scoop affecting cards- 4 scoops to nuke 1 of someone else.

In comparison thief gives a net benefit of 2- +1 for you in your choice and -1 for your competitor and of course modest improvement allows you to make late min scoop runs.

Peeping Tom offers virtual no benefit in comparison to it’s costs and seems mainly used to annoy other players rather than offering any real tactical benefit.

If CZ wanted to upgrade the utility of Destroyer I’d suggest having it nuke 2 scoops of the players choice and ignore the effect of shields. That way you can effectively use it to punch through the defenses of someone doing a min scoop shield combo.
