Balance comparison:
Firefly Queen, unupped: 3|7 for 6
, 3|2 (luminescent) for 2
upped: 3|7 for 6
, 4|2 (incandescent) for 2
Pharaoh, unupped: 4|9 for 9
, 2|1 (swarm/devour) for 2
upped: 4|9 for 9
, 3|1 (swarm/devour) for 2
Cyclops, unupped: 3|6 for 5
, 2-4|1-4 (avg. 2.8|2.5) for 2
upped: 3|6 for 5
, 4-7|1-6 (avg. 5.6|3.2) for 2
Because upped other weapons have double the average attack of unupped other weapons, I'd consider increasing the upped cyclops cost by one or two. The unupped looks balanced to me.
