I wanted to take advantage of Embiggen but give it some more control aspects. Turns out that an Embiggen dragon package coupled with a quest package is a very viable build that I haven't seen anybody playing.
There is a lot of value here and a ton of swingy turns that can do ridiculous things. Embiggen into Frizz into Embiggen into Floop for example. The Quest + Embiggen into Oasis Surger makes Faceless Corrupter look silly. You get the idea.
If this gets any attention I'll do a write up on how to play the deck optimally. There are a few flex cards here that I am still mulling over but this is a decent list already. Enjoy!
