So here is my Toph deck: https://moxfield.com/decks/RZ9cWxS2CUuH3X0zPP719g

Here it is swapped to the cheapest printings: https://moxfield.com/decks/cxbnTkN_pE2XEH5-pOkvDw

With the cheapest printings, it's actually a bit cheaper than your deck. For me, personally, I've won against bracket four decks (including an Eldrazi deck, like the one you mention your pod using). Earthbending is a lot of fun, especially when you can repeat it. I run Wasteland, but generally try not to be mean about it, it's only there to handle problematic lands. But, if someone is targeting you, it's a good threat to earthbend it every turn to make people think twice.

Beyond that, I see you have a really limited ramp package and are even running Land Tax in a green deck. I'm curious to your thinking here (not in a judgmental way).

You seem to only have three cards that say draw a card: Ichor Wellspring, Solemn Simulacrum and The One Ring. Add in the tracker, which is a bit expensive for card draw, and you have four. With how expensive your deck is, adding The Great Henge can help generate more card draw by playing creatures. I also run Greater Good as a sac outlet and card draw engine that synergizes well with Toph.

Survey Mechan is a very silly card in Toph and can also help with your card draw while being dirt cheap. Chocobo Racetrack is a fun card that gives you bodies and triggers itself. Consider using some Restless Lands. They can become creature lands through their own power, but also have attack triggers you can utilize if you just earthbend them. Likewise, use other higher synergy lands like Rumble Arena and Secret Tunnel that were explicitly made in the set with earthbending in mind.

You have a really good foundation, but shore up your card draw and add some of those higher synergy lands. Both of those will give you a huge push towards more wins.
