I think awoken indra is a great utility to have, and he covers light and green which is nice. I personally always favor TPA and haste cards on my fenrir teams just because they tend to fit into his play style better. But please feel free to experiment and let us know I don't think I would pair Aten and Jorm leaders since Jorm boosts green attribute. However Aten+Gaianut doesn't sound like a bad idea at all. I still feel that a Fenrir+Aten pairing can also work out. Sure you drop to x125 max damage but the larger board for rainbow jammer leaders (or any of them really) is just such a nice luxury to have. Aten also brings a board change with him and all those killer awakenings. So hopefully one day I can pull that guy and give the mismatch pair a try!
