How long do you think it will be before we see enough cards to build a playable Aegon deck?
I'm thinking that Fiefdoms, Great Pyramid, Temple of the Graces etc. could still be used from standard Targ sets. Just no Dothraki or Dragons.
It would probably make sense to run Treaty with the South, a Dornish alliance seems to be the smallest stretch of the imagination which would bulk out the card pool.
what essentials would there be to make the deck worthwhile, not just a generic targ/martell alliance?
