Powerful Gruul threats like Frenzied Arynx make Orzhov Racketeers look puny and can plow through little spirit tokenseven if they trade, the Gruul player gets more damage in
The others either pushed an archetype that was already strong in their colors (like Mono-White's pro-equipment) or just didn't do anything new
I also really like Garruks Uprising
Gadrak is one part Anax, Hardened in the Forge and one part Teshar, Ancestors Apostle, but Ive decided to add a dash of Ravager Affinity meets Ironworks combo. There are several loops available for a combo finish, which often involve cycling two Junk Diver variants with either a Krark-Clan Ironworks or Ashnods Altar (occasionally requiring a cost reducer)
Weve all been there, and I think we can all agree games that play out in this fashion suck
I hope this has been helpful in organizing your Magic sales, and good luck on joining the fray!
