Hi there.
I'm still quite new to the game, just picked it up a couple of months ago but absolutely loving it. I have clearly seen and understand the benefits of having 2 Core sets and 2 EoD sets in order to have a consistent competitive deck.
However (since I have trouble with limiting my choices of objective sets) I often struggle with resisting the overwhelming temptation to put in an 11th OS here and there. I know that one may/could say that the 11th OS "dilutes" the deck but I like the extra ships, chars or resources and often I see that it works, possibly with a "lucky draw" but still.
One example is this deck, apparently similar to the deck that So Cal group brought to Worlds but with an added Alderaan Promise OS:
Afflilation:
Smugglers and Spies (Core)
Total Objective Sets: 11
2x The Defense of Yavin 4 (Core 8-1)
Red Two (Core 8-2)
Y-Wing (Core 8-3)
Astromech Droid Upgrade (Core 8-4)
Hidden Outpost (Core 8-5)
Rebel Assault (Core 8-6)
2x The Rebel Fleet (Core 11-1)
Home One (Core 11-2)
Y-Wing (Core 11-3)
Repair Droid (Core 11-4)
Hidden Outpost (Core 11-5)
Target of Opportunity (Core 11-6)
2x Prepare for Evacuation (A Dark Time 49-1)

2x Attack Pattern Delta (The Battle of Hoth 59-1)
Rogue Leader (The Battle of Hoth 59-2)
Rogue Two (The Battle of Hoth 59-3)
Snowspeeder (The Battle of Hoth 59-4)
Snowspeeder Launch Bay (The Battle of Hoth 59-5)

2x Asteroid Sanctuary (Edge of Darkness 72-1)
Millennium Falcon (Edge of Darkness 72-2)
Cloud City Operative (Edge of Darkness 72-3)
Cloud City Guest Quarters (Edge of Darkness 72-4)
Bamboozle (Edge of Darkness 72-5)
Twist of Fate (Edge of Darkness 72-6)
1x Alderaan's Promise (Edge of Darkness 77-1)
Bail Organa (Edge of Darkness 77-2)
Tantive IV (Edge of Darkness 77-3)
Alderaanian Artist (Edge of Darkness 77-4)
Diplomatic Presence (Edge of Darkness 77-5)
Misdirection (Edge of Darkness 77-6)
Hopefully get some resource enhancements on the board or discard (Defense of Yavin 4) in order to get those big ships out in play.
What are your thought?
