Welcome back to the game, and you have a good idea to come here to the forum to get deck advice. Be warned that most people will probably give a LOT of suggestions, and you probably don't have a lot of those cards yet. This offense wouldn't win any big tournaments, but it could still be a lot of fun to play around with as long as your current opponent/s are on a similar level to yourself.
You do have some really good cards in there (Seeker of the Lost, Ark of the Covenant, Israelite Archer, Michael's Sword, and Darius Decree), but I would generally recommend that for newer players that you try to build an offense that is all 1 brigade so that your enhancements and characters always match when you need them to. I would recommend that you have about 9 heroes, and about 9 good enhancements.
Given what you've listed, I would probably choose to focus on Blue.
Noah
Noah's Sons (I know their not blue, but the help Noah)
Seeker of the Lost
Eve
Israelite Archer (I know he's not blue either, but he could just kamakazi to take out 1 EC, or he could band to a weapon-class blue hero if you have one)
4 more blue heroes that you have
Covenant of Noah
Jacob's Rods
Courage
Holy Ground (I know it's not blue, but Seeker can use it to negate)
Burning up the Chaff
4 other blue enhancements that you have
Artifacts
Priestly Crown - to have site access
Ark of the Covenant - to take out a couple of ECs
Holy of Holies - so that Moses and KoT don't kill you
King's Sword - so Red Dragon isn't invincible to you
Darius Decree - so ET doesn't kill you
Then to get you offense supersized, I would buy the tins of Genesis stuff from FooF and RoA. If I remember there were 3 tins, and that should get you about all you need. It'll also get you a bunch of booster packs that could have other cards for your defense, etc.
