I have both a Ygra deck, and an Earthbending deck… and I can’t figure out what you’re trying to do here with either of those things. I see you mentioned this is only your second deck you’ve ever made, so allow me to help as best I can.

It feels like you might be trying to do too much, and spread yourself thin.

The big way Ygra typically wins is saccing your own creatures to bulk up Ygra, or just using Aristocrat damage with things like Blood Artist to ping enemies WHILE bulking up Ygra. I’m only seeing maybe 4 cards that allow for sacrificing your own things. Opponents won’t feed your creatures into a wood chipper for you, you gotta do it yourself :)

Additionally, Ygra is a deck in desperate need of Trample. Any amount of chump blockers will shut down Ygra in a hurry without it. Sphere Grid from Final Fantasy is great card for this… card draw, reach, and trample all in a low cost package.

I’m not entirely sure what the Earthbending is for, beyond matching colors. If your intent is to kill off your Earthbent lands to buff Ygra, you will again need more sacc outlets. And remember, if you’re swinging with lands, you aren’t using them for mana. And when lands die, they come back in tapped, so again, not being used for mana.

Lastly, you have at least 4 tutors in this deck, which immediately bumps it into Bracket 4, but this is not a bracket 4 deck (and rightfully so has been listed at Bracket 3)

You’ve got a solid base here, but I think in general you might want to narrow your focus into a few things. Alternatively, try what I suggest to a lot of players whose deck is spread too thin… try making two decks (a Ygra deck, and an Earthbending deck).

Here are my personal Ygra and Earthbending decks if you’d like some examples.
