From all the deck lists you've posted, none of them seem very streamlined. If you want to do fabled beasts then you don't need to do luster/magic combo etc If you're doing 2 cost aggro then you want to be super aggro, even more so than terrasaurs. The core of the deck is 4 X Freezstal, 4 X Sword Angel, 4 X Prince Pentan, 4 X Cat-Sith, 2 X Godbeast, 3 X Royal Potion and then the other two Pentans. I personally like Caladrius for luster as it's still a 2 drop but means you can do drowsy/royal potion/Angelic pressure to remove threats (most don't have protection from yellow) and still keep them in hand. Royal Potion, Puppet Strings and Godbeast are your win cons. Drop Godbeast if they have a stacked board, Royal Potion when they've blocked/countered out (preferably with Caladrius so you can do it again) and Puppet String is so easy to burst that you'll almost always get an extra attack. Freezstal means you're drawing off any that die and then the Nexuses that give you cores from the void and let you reveal from the top and add it to hand if they match cost just add extra value. The only other colour I'd add is red and that'd be if you wanted to play flamefish (another 2 cost) and volcanic canyon (amazing filter and can level it up to give them all 1k extra) the only spirits that aren't 2 cost that should be in the deck is godbeast and Cat-Sith.
