Where each ORIGINAL Epic Duels deck in a 2v2 game would fit into these tiers.

Tier 1A: Untweaked Obi-Wan. Original Obi-Wan is hands down the best, most consistent 2v2 player in the game, especially with his ridiculous FORCE CONTROL card.  He was in a class by himself.  If he was still around in his unaltered form, he’d be in a class with Darth Sidious, Yoda Kashyyk and Master Windu.

Tier 1B:  Emperor Palpatine. There’s a gap between Obi and Emperor.  The original Emperor is included in this tier.

Tier 2A:  Darth Maul.  There’s another gap between original Emperor and original Maul, who is included in this tier.  I know some groups think Maul is nearly as good as Obi-Wan but in our play experience, he was always a tad weaker than Obi and is not as solid a teammate as Emperor Palpatine, who has strong minors and damage from anywhere.  Still, Maul is better than Anakin/Dooku/Mace.

Tier 2B:  Untweaked Anakin/Dooku/Mace and to many, including our group, Yoda.  This tier includes original Anakin.

Tier 2C:  Untweaked Boba Fett.  I know I’ve seen players who value original Boba Fett almost as high as Anakin/Dooku/Mace, but others who would put him at Han’s level.  Let’s call him somewhere in between that.  Our group would probably include unaltered Luke & Leia here too, though we’ve always valued Luke a little more highly than others.

Tier 3A:  Han Solo.  Boba and Han are both clearly better than Jango, that much isn’t really debatable.  Han is probably not quite as good as Boba, though.  Vader might fit into this tier as well.

Tier 3B:  Untweaked Jango.  Jango really belongs here by himself among the original decks, though Vader might join him.

Notes:

• Tier 1A:  Darth Sidious is intended to be the strongest deck, about as good as original Obi-Wan. Yoda of Kashyyk and Mace are intended to be up there with him. Mace Windu is the best pure melee fighter, and might be the best deck overall, but Sidious is a better teammate than he or Yoda due to his direct damage from anywhere. Yoda’s Wookies make him a better teammate than Mace.
• Tier 1B exists because every time we game, we like to do a “Battle for the Universe” with Darth Sidious vs. Yoda of Kashyyk and each with a teammate, but it never works out if Mace is Yoda’s teammate because there’s no fourth deck strong enough to go with those 3. Meanwhile, decks like Darth Vader Jedi Hunter and Dark Side Anakin can really dominate against weaker foes and certain types of decks. Obi-Wan’s offense is watered down but he hasn’t lost a lick of defense, while both original Emperor Palpatine and a powered-up Dooku are great, great teammates.
• Tier 2A is probably the hardest to define but the best way to put it is:  These decks can potentially dominate a game, even against the toughest opponents, but they don’t do it consistently enough to be Tier 1. To us, this includes the original Darth Maul. I know Epic duelists who think he’s great and Tier 1, and there are solid statistics in how well Maul performs in 1v1, but in 2v2, our group has never found Maul to be consistently be among the best decks. It’s important to note that this was true within that first week of us playing the game, well before we started adding decks to the set, and has remained true. At the same time, we think Maul is definitely better than original Dooku, Mace and Anakin. He has a Tier 1 ceiling but can’t consistently hang with the best decks and isn’t a great teammate, in our opinion. Quinlan, Shaak Ti and Plo Koon are all Tier 2A decks, a little better than Tier 2B. As such, these 3 Jedi decks are probably higher powered than where they probably should be based on their characters, but we like the decks and aren’t inclined to change them much at this point. All 3 have been powered down already over the years but remain capable of dominance.  So are Qui-Gon and Luminara, but that’s more where we intended for them to be due to their Jedi Padawan minors.
• Tier 2B decks are your standard Tier 2 decks, about as strong as original, unaltered Dooku or Mace and includes original Anakin (who we’ve always like a tad better than Dooku or Mace). These are otherwise your standard Jedi like Aayla Secura, Ki-Aid-Mundi and Saesee Tiin & Agen Kolar. Nute Gunray is there too, probably a tad stronger than we intended, but was tweaked for a GenCon Tournament and needed to be Tier 2B for it, and we’ve stuck with that version. With the possible exception of Nute, our Boba & Dengar deck is the strongest shooter in the set and belongs in this Tier. In 3v3, that might be the best deck overall.
• Tier 2C is another tricky one, and some of these decks could probably go up or down a tier. As of this writing, all of our Tier 2C are melee decks that just don’t have quite as much in terms of overall staying power or offsetting killing power to hang consistently with Tier 2B decks, but it’s a coincidence and there may be some Tier 3A shooters who belong here, and Finn & Poe probably do. Of the original Hasbro decks, Boba & Greedo would fit here, likely a tad stronger than original Han, but not able to make the cut in a straight Tier 2 tournament. We’d probably put original Luke in this category too, who has dominated 2v2 games with I WILL NOT FIGHT YOU, and with Leia surviving in a 2v2 game, is probably a tad better than Han. All of these decks, of course, can do things and all are capable of winning games, but I can just tell you that when playing against Tier 2B decks, Asajj routinely gets her head kicked in, while Old Ben and Bultar Swan have their moments but more often look outmatched. All could play in a Tier 2 tournament, some of these might even turn out to be Tier 2B decks once we get more games in with them. However, none of these decks are really capable of dominating a game except maybe Jabba — who is quite fragile — and all including Jabba could also turn out to be Tier 3A decks. That’s how some people see the original Boba and Luke decks as well.
• Tier 3A decks could probably sneak into a Tier 2 tournament and not look wholly out of place, if you believe that about good old, unaltered Han & Chewie, who reside in this Tier. Even if you’re not sure about that, Han is definitely better than Jango, and they belong in different tiers. These decks are all shooters but what they have in common is that the best game out of any of these decks is really, really good, and they’re not quite as fragile as the Bounty Hunter decks. Our tweaked Jango & Zam remain fragile, but at least have added offense to go with their trademark superior movement, enough to be more competitive with Han & Chewie at least.
• Tier 3B decks like IG-88 and Lando typically get blown to smithereens early but when they don’t, they’ve dominated games. We don’t want to get into having any characters incapable of playing any others, so as all these decks have low HP and Yellow decks, they have to be very, very dangerous, or risk being completely worthless in a game of Epic Duels. The idea is that original Jango & Zam — in the opinion of our group, clearly the weakest original deck — would fit into this Tier but I’m not even sure that original deck could hang here (though they do have great movement).
• Greedo is intended to be the weakest deck, but even his deck has 1x A10, 2x A8, 2x A6 if not blocked, and 2x cards that don’t let you block the next attack, so it is quite possible for him to defeat Darth Sidious in a straight 1v1 match, if he gets the right draw and Sidious gets a bad one. The quick description probably makes the deck sound stronger than it is, but with cards spread across 3 characters, and 2 of the big attacks having severe penalties, it’s hard for Greedo to get much going with any consistency. The point is it CAN be done, and that’s how it needs to be.
