As an Abzan Reanimator player, there are very few things I don't want to be paired against. Fliers plus sweepers are problematic, as is Hushwing Gryff in general. Planeswalkers also pose a bit of a problem, assuming my opponent can protect them reasonably well.
Tzio has Wingmate Roc maindeck and Stormbreath Dragon in the sideboard, both of which pose a problem unless I can find a Hornet Queen. Some Naya decks have Anger of the Gods to beat Hornet Queen, while Tzio opted for the more conservative Hushwing Gryff, which might be an even bigger problem.
Against the rest of the field, Naya functions similarly to an Abzan Midrange deck, with Courser of Kruphix plus removal to survive the earlygame and planeswalkers to thrive in the lategame. With Whip of Erebos decks performing well, you might want to consider trying something like this.
