Good question. Here's the way I would interpret it: "The second and third players to claim the battlefield do not take control of it and do not use its “Claim” ability." I can infer from this that FFG probably intended the first person to claim the battlefield would use its claim ability, even if they already control it. As a result, the following sentence is two clauses, separated by a "|": "When a player claims the battlefield, if they do not control it, they take control of it | and may use its “Claim” ability." If they don't control it, they take control of it. Then they may use its claim ability. On top of it, they get to choose one of the three face-up set-aside battlefields and use it. So, in short, the person who claims the battlefield first takes control of the battlefield and gets to use two total claim abilities: the one on the battlefield in play, and one on one of the three set-aside face-up battlefields. The second and third players to claim the battlefield do not take control of it, but they may use the claim ability on one of the remaining set-aside face-up battlefields. Hope this helps!

Art of War states, "Spot a Red character to reveal an opponent's hand. For each card just revealed, remove a die showing a value that is equal to that card's cost." Since it doesn't specify that you have to remove an opponent's dice, if you reveal a card that costs 2, and your opponent doesn't have any dice with a value of 2 in their pool but you do, do you have to remove your die? Note: I feel like I already asked this, but I'm too lazy to check XD

So, Destiny doesn't deal with the Legacy Universe. It does OT, ST and PT. And there isn't going to be a set that focuses specifically on one of the trilogies; rather, each set has a balanced mix of all three. So if you want a Vader deck, there are Vaders in Awakenings, Spirit of Rebellion, and Across the Galaxy. Spirit of Rebellion definitely has some outstanding OT characters IMO, and if you can get Awakenings, then do (it's my favorite set). If you want a balanced pool, I would steer clear of the newer sets, as everything they throw out there is above and beyond overpowered compared to the first 3-4 sets. Definitely get Aw, SoR, EaW, and Leg, and if you want to then you can go higher from there as well. And 3 boxes isn't always enough, tbh: if you want to be "set" for a set of cards, you'll need at least 6-8 boxes lmao.

Pokémon will live forever. Change my mind. I was super sad when I saw that it was canceled. My dad and I have loved playing it, and have been doing so since Spirit of Rebellion was released. Since I'm not extremely athletic, it's been a really great way for us to bond. Thankfully, FFG released the Transformations print-and-play, and numerous mini sets have been released by fans, so although the production has been stopped, my guess is its legacy shall remain.

To answer all of your questions: 1. I would NOT recommend Rivals or Allies of Necessity; they're not good for casual playing, and in fact I've rarely used any of the cards in Allies--and I've played an extremely wide range of decks. My favorite sets are Legacies and Awakenings. Would definitely recommend. Empire at War is probably the only set I would not recommend, but that's just because very few of the cards actually synergize well. It's also a very offense-oriented set, whereas I'm a defensive player. Still get it, though; it's best to fill out your collection. 2. Yes, the starter characters are average to good (aside from maybe the Grievous starter characters; they're pretty situational and can be good, but it's not a great starter deck). Idk what E.U. means lol 3. DEFINITELY double up. You don't need to triple, but you can if you want. 4. If you get the Boba starter, get the Obi-Wan starter too (the one with Han Solo). 5. Get two copies of the two player starter. Each of the characters only comes with one die, and you'll find yourself begging for a second copy of many of the cards. 6. See #1. Hope this helps! If you have any more questions don't be afraid to ask.

Would I be able to, say, decrease 0-0-0's cost by 2 by using a combination of Reprogram and Doctor Aphra's ability?

This is epic! A few wording suggestions: 1. Revan: "They may not be removed until the round ends." 2. Darth Malak: careful with the wording here. Technically, this would mean that your other character would be saved from death by Malak suffering...exactly 0 damage, almost every time. Reason? Only when the character has damage on it equal to or greater than its health is it defeated. Example: opponent deals 2 damage to your...uh, Servant of the Dark Side I guess. Before this damage was dealt, he had 1 remaining health. 2 damage is placed on him. Then, since he has no remaining health, he is defeated. But wait--Malak's ability triggers! He is dealt 0 damage--since Servant has no remaining health--and Servant stays in the game. I don't know what to do about this exactly, but I'm sure you'll figure it out. 3. Force Drain: "...to defeat one of your characters and heal all damage from a character." 4. Sith Marauder: "...for every 4 Blue upgrades in your deck, to a maximum of 3 (rounded down)." 5. Omens of the Future: you could probably remove the "choose one of the following" and then you could fit "unblockable damage to a character" onto the card. 6. Star Forge: watch the "your" in the first sentence. Should be "you." 7. Zaalbar: "...to deal damage to a character equal to its cost." Maybe shorten the quote to fit this in there. 8. Ebon Hawk: "Play an upgrade from your hand for free. Discard that upgrade after the round ends." 9.T3-M4: "...to an opponent." 3 player games are a thing. 10. Oath of Valor: "After that character is defeated, set this support aside and increase..." 11. Stand as One: "Before an opponent deals damage to one of your characters, you may prevent that damage if one or more of your characters was defeated by that opponent during the last round." Of course, this is how I would put it, so you don't have to do that. I'm outta time for now, so I'll write down card balancing and stuff tomorrow.

Well, the starter decks are always winners--however, they only come with like 20 cards and character points, but you can add cards from the corresponding set and you can usually add dice until the character point total is at most 2 less than 30 e.g. for the Luke/Han starter set, make Luke and Han both elite and add 10 more cards from Legacies.
