Quoted from original builder ShinyBluePen on Reddit (https://www.reddit.com/r/EternalCardGame/comments/7rfj44/combo_party_v2/, slightly edited formatting):
"The key of the deck is
Scouting Party. Virtually everything in the deck is about making it happen with
Wump, Party Starter or
Calderan Gunsmith. The
Jotun Feast-Callers are MVP. If you get three attacks with one, gg, your opponent will never come back from your answers, and counterspell really shuts down enemy shenanigans.
West-Wind Herald is also fun with gunsmith, allowing the exodia combo if you get the pieces. In your opening hand you almost always want at least three power sources and draw/removal.
Let me know if you have any questions or suggestions, and have fun! The deck's a blast!"
+1 wisdom
+1 strategize
+1 herald
If you have the stone, they're a good craft, and go pretty well into almost any blue deck.
