edit: This version of Shimmerpack by Collector is a lot better. Go play it, not my version. https://eternalwarcry.com/decks/details/5LG6HRGo-XY/collectors-deck-1st
I took this deck from about top 100 to top 15 on ladder. It was also my ECQ deck but I only went 16-12 and struggled against the higher number of aggro decks that aren't present in the top of ladder. I designed it to beat the slower, non-mainboard-Harsh Rule FJS decks and other clunky slow things that exist at the top of ladder. I would not recommend this deck for anyone laddering at all unless they just want to play something different for fun.
Most important part is to make sure your Shimmerpacks have either Berserk or Flying (or both). Consider holding a merchant and an inspire unit until you can play them both in the same turn. I tried a couple other cards, including Alhed, and they seemed good but hard to say which was best.
