If Bandai offers a Pre-release for this set, by Pre-Ordering Kingdoms of Intrigue [OP-04] Booster Boxes you MAY be able to pick-up some, if not all, of your Pre-Order during the Pre-Release weekend which is typically 1 week before the actual Release Date (while Pre-release supplies last)
So you can get around Seismitoad-EX and Trevenant and Wobbuffet with Unown because it still draws cards under those effects, which is a good plus
Summon: Primal Odin My biggest concern for the Summons is that they are all quite expensive, Primal Odin included, and being not only creatures, but enchantments as well, makes them seem extremely easy to get rid of
In this case, Conspicuous Snoop is the latest addition, and it does an awful lot for a very low cost
He will double your goblins and, if nothing else, give you chump blockers while you amass an army of slimy little goblins to play with.
This puts so much pressure on your opponent to have the right defenses
