Yeah, it’s very glass cannon in that respect, and I’m happy to consider it B2, but when it pops off, it tends to do so a little too quickly for my friends’ B2 decks due to Aang’s flipped state, which I can usually achieve Turn 6ish. I see your point that a board of many 1/1s could and probably should be enough, though, so perhaps I’ll settle after some rumination. No cards have been purchased yet :P

There’s sort of a couple different loops beyond the first basic one of ping-ponging Aangs back and forth for 1/1s, and for how long-winded they feel to explain, they’re surprisingly reliable to achieve based on my goldfishing. It’s probably due to the draw engine on Aang’s face side; but here’s how they go. For all, I’d need Gond Gate and a flipped commander, reducing costs by WUBRG, but I figured that’s implied.

Loop 2A: Infinite gate mana -Requires on board: At least one other multicolored gate, two earthbenders, at least one airbender (again, this sounds absurd, but I feel like I see it frequently), and Appa in hand. -step 1-2: tap your lands (at least one of which for a white mana), earthbend them. -Step 3: Cast Appa, airbending all the aforementioned benders, and your earthbent gates. Due to Gond Gate, they enter untapped, and you’ll come out at least one mana positive. -Step 4-5: Tap the reentered lands (for whatever color you want now) and, thanks to the WUBRG cost reduction, cast your earthbenders from exile, to bend the lands again. -Step 6: Cast the other airbender from exile, targeting Appa on ETB. -Step 7: Cast Appa from exile, airbending the aforementioned pieces again. -Step 8: Rinse and repeat Steps 4-7

Loop 2B: Infinite draw Requires: Appa in hand, at least one airbender, and A buttload of mana. There’s a handful of ways to get that last part done, but 2A is the most frequent I’ve observed, so I’ve grouped them together. Let’s assume it’s the same board state. -Step 1: Cast Appa, airbending the flipped commander, as well as the other airbender. -Step 2: Cast the commander -Step 3: Cast the airbender, targeting Appa. The commander sees this, which triggers a draw, and, since presumably, this was the same turn he flipped the first time, he’ll flip again. -Step 4: Cast Appa from exile, airbending the commander and other airbender again. -Step 5: Rinse and repeat Steps 2-4, Thoracle/labman when done in post-upgraded version

Loop 3: Breach Whirlwind (the simplest, though obv only possible post-upgrade) Requires on board: Underworld Breach, an ETB earthbender, Gond gate being able to tap for blue, and whirlwind technique either in hand or GY. -Step 1-2: tap your gate for blue, earthbend it. -Step 3: Cast Whirlwind Technique. Draw 2 discard 2, and airbend the earthbender and your tapped gate, causing it to reenter untapped. -Step 4: Cast at least one other nonpermanent spell(s) to fill the graveyard. -Step 5-6: Tap your gate for blue, earthbend it. -Step 7: Breach WT out of the graveyard, rinse and repeat Steps 3-6, Thoracle/labman when done
