When Siona enters, look at the top seven cards of your library. You may reveal an Aura card from among them and put it into your hand. Put the rest on the bottom of your library in a random order.
Whenever an Aura you control becomes attached to a creature you control, create a 1/1 white Human Soldier creature token.
Build a wide board by suiting up creatures with cheap Auras, generating a 1/1 Soldier token each time an Aura attaches. Snowball with token doublers and Aura recursion, then alpha strike or combo off with free-attaching Auras. Siona digs for your best Aura on entry, so you always have a Voltron payoff or a combo piece in hand.
Add an infinite token combo (Shielded by Faith plus a repeatable reattach/flicker outlet) and a finisher like Craterhoof Behemoth so the wide board converts immediately. Improve mana with fast rocks and untappers, and lean into Enchantress draw (Sram, Setessan Champion, Sythis) to offset Aura card disadvantage. Round out with protection like Heroic Intervention and Teferi's Protection to survive the board wipes that punish Aura decks.
