Nice list! Have you considered using cards like Unbreakable Formation , Make a Stand and Heroic Intervention to protect yourself from board wipes? My Huatli deck is somewhat similar to yours and I have found the said cards to be quite effective.

Megalomania those are great suggestions! I considered about putting in Heroic Intervention . I thought that I could get along with just Fresh Meat , but I guess that one card for protection will not be enough, so I'll rethink that. Thanks for replying!

hmm doubling season oathbreaker without a planeswalker who can ult the turn they come down, imagine this deck with slight changes to the mana base with Tamiyo, Field Researcher as the oathbreaker. with season out the turn she comes down you just get a Omniscience , her +1 is pretty good levels of card draw, her - 2 can protect herself, open an opponent to attack, or slow opponent's strategies. of the possible planeswalkers huatli may just be the weakest two options for these colors for this strategy.

Now outside of that my main thought would be to maybe not show off your plans to win with your signature spell, maybe run it in the deck normally and run a tutor like Enlightened Tutor where you can toolbox your kit while also being a spell you'd like to cast more than once a game (though any g/w tutor spell can work well).

Now the topend of your deck is really mana hungry, Cryptolith Rite and Druids' Repository can help you with that goal.

Demarge okay that is a detailled breakdown, so first of all, thank you. You got some very good points with the transparency of my gameplan. That is an aspect I really did not think of until now. Tamiyo, Field Researcher is also a great suggestion as an alternative oathbreaker, I will definetely try some builds with the same strategy!
