In an earlier chat discussion with Rey on the concept of an Aura deck in Standard, I have thought that Blue White is not the only option for this archetype. That is because Core Set 2019 has provided two relevant creatures that gains value with this build, namely Vine Mare and Satyr Enchanter. Going to the Green White route and coupled with the Cartouches in Amonkhet and a few new Aura options, I have formulated this decklist below.

Creatures
4 Novice Knight
4 Satyr Enchanter
4 Vine Mare
1 Lyra Dawnbringer
2 Danitha Capashen, Paragon
3 Sram, Senior Edificer
2 Shalai, Voice of Plenty

Spells
3 Blossoming Defense
2 Cartouche of Solidarity
2 Cast Out
4 Cartouche of Strength
2 On Serra’s Wings
1 Seal Away
2 Trial of Strength
1 Thopter Arrest

Lands
7 Plains
6 Forest
2 Tranquil Expanse
4 Sunpetal Grove
4 Scattered Groves
