Arkbrave isn't going to be relevant until we get better dragons and/or an easier way to special summon Arkbrave itself from the graveyard to non targeted banish faceups (namely Onslaught and SSA).
The best builds use 3 x White Night Dragon 3 x Arkbrave in conjunction with Grass is Greener and Needlebug Nests to mill for special summons.
You can try using the mokuba reward card "ruins of the divine dragons" with the paladins, can make a 1 turn dragon and the eff negation is good agains most meta decks. While arkbrave itself is good agains some decks like amazoness and fa because of the backrow removal
A pretty good version of a Grass is Greener/Needlebug Nest Arkbrave deck I saw the other day combined with Lightsworn (Lyla for mill and removal, Wulf who special summons when milled). Also had 3 White Night Dragon, 3 Arkbrave and 3 Canadias, along with Paladin and Ruins as mentioned above. It was very consistent at getting 2100+ monsters out each turn. Kaiba levels of expensive though.
