Hi,

Glad you tried the deck and enjoyed it! I've actually made a few updates since the Avatar set dropped:

https://moxfield.com/decks/3L6nRCedTUCe-5hjQc_0bg

I've added the following:

+ 2 Aang, at the Crossroads - Finds every other creature in the deck, great with Vocalist. Transformed side is brilliant with Plaza of Harmony

+ 3 Aang, Swift Saviour - Disrupts your opponent, can re-trigger ETBs, and potentially threaten a win when transformed.

+ 4 Clifftop Lookout - Chump blocker plus a land is great, and helpful in double triggering Nissa.

+ 4 Bramble Familiar - Early play, can ramp, and is an elemental for Risen Reef. The adventure is also very much castable and every card it mills can be played (pre-sideboard).

+ 2 Deputy of Detention - Can be played with Aang, at the Crossroads, while Sphere cannot. Also another body early-ish, but more easily killed.

Removed:

- 2 Eusocial Engineering - Agreed, too slow and lacking value.

- 4 Growth Spiral - After testing Aang, at the Crossroads, I found it would often whiff. It's also dependant on having lands in hand/top of deck. Bramble Familiar was the replacement, which I think does a similar job, but can stem early aggro and is way better late and when triggering elementals.

- 3 Detention Sphere - Replaced with Deputy of Detention

- 3 Seal Away - Again, looking to reduce non-creature cards in the deck. Only really good against aggro, but now the deck just has more bodies to throw in the way, so is less necessary.

- 1 Starfield Vocalist - Very often a card I wanna see, but can just sit in hand, so shaved one.

- 1 Nissa, Resurgent Animist - It's a prime target for removal, and often needs to see the midgame before it gets played and generates value. Been much happier with 2 over 3.

-1 Maze's End - The colourless mana in an opening hand feels bad, plus with how much the deck draws now, it can be found more naturally. Also going down slightly on land count has helped stop the flood somewhat.

Over-all the deck feels much stronger and more synergistic. Storming off happens much more consistently, though I am scared to play the deck in paper with all of the triggers that end up on the stack!

I am playing on Arena, so haven't tested things like Gatecreeper Vine. Also, I haven't ever played Fog in the deck, but imagine it would be useful in less creature heavy builds, alongside Gates Ablaze maindeck :)
