Now I've got "Secret Agent Man" going through my head. Lol...
I like it. Useful ability and it makes a nice thematic tie-in to both elements.
Cloak mechanics seem a little underused since its cost makes splash usage difficult.
This card will open up the mechanic to a wider range of strategies I think. Should be quite fun.
It will also be very fun to use in conjunction with cloak. That way, the opponent cant just shoot your cloak to get at everything underneath. That will make the "Removes Invisibility" mechanic much more useful.
