This weekend's tournament at my local shop is 300 points and only pieces from Flash or GotG, and I'm just looking for some ideas on pieces or teams to build. I'm a pretty big fan of Jenny Sparks and have all Authorities other than Jenny Quantum and Engineer. Also have a fair deal of Rogues that could be pretty decent.

Really just trying to find some starting points and bounce around some ideas. Thanks in advance for any help!

I would go with Sphinx and Cpt. marvel PRIME from GotG. Leaves 28 points for a resource and they work well together. or rogues:

110
FL054 Abra Kadabra

68
FL026 Rainbow Raider

70
FL022 Trickster

40
BM006 Hired Henchman
288

I don't think resources are being allowed, to my knowledge there are no resources within those two sets. Even still I'm pretty recently returning from a three year hiatus and my one resource is the Infinity Gauntlet.

The Sphinx + Marvel combo seems pretty legit. I have access to both of those pieces. Do you think fielding a FL006 Central City Police Officer in those last 28 points would be solid? If you can manage the positioning you he would benefit both fairly well.

As for Rogues I don't have access to an Abra Kadabra, nor the Henchmen even if he was in the sets. The Rogues I do have are as follows:

012 Captain Boomerang
013 Trickster
014 Girder
021 Pied Piper
022 Trickster
023 Captain Boomerang
025 Golden Glider
026 Rainbow Raider
027 Reverse-Flash
028 Tarpit
038 Captain Cold
039 Dr. Alchemy
040 Weather Wizard
043 Murmur
207 Golden Glider

+ the Fast Forces: Rogues pieces
