And that's why another EE was proposed. There are many Monoairs with 2 EE's, 2 Fogs and 5-6 SoFree's circulating (and posted). If you want to have a shot against Arena, you definitely want 5-6 SoFree and Fogs. Wings is weak on its own as Dragons and other airborne creatures are everywhere. Against Elders.. you can run almost anything.
In Arena i won 2 Spins at Gold (I played for a while and isn't effective), it is average at Silver and efficient in Bronze. I wanted to post that this deck is effective to farm Half-Blood AI because it doesn't have an strategy like AI Level 3 and you could win an upgraded card at Spins But i wouldn't use it from PvP or Arena for Farming, only testing.
however, SoFree rushes with just quanta/shards/creatures that we've mentioned do well in arena. Note: Chaos Power/Wyrms/SoFree/damselflies/quanta deck is one of the top arena farmers.
You remind me a deck, but i don't remember the name... It's about spamming Sofr and Deja Vus with Adrenaline, it also has cards like Blessing, Chaos Power and Quintessence depending at customization. It should be a faster farmer.
