Best marshal archetype feats for a thaumaturge?

Going into a game with this combo, and while it looks synergistic, I may want to get out of it ASAP for others.

Since I've heard Thaum is action-hungry, which feats of this archetype are the best value? I assume the aura is a must-have, since it's ideally only one action per fight, but the rest seem more demanding, situational, or else compete with reactions you'd rather use on implements.

Snap Out of It is extremely good, borderline broken.

Late to the party I know, but I've got a Mirror/Amulet Thaumaturge in the works who's also taking the Martial archetype.

I realised that the main advantage of the Mirror is that it lets you take reactions from multiple places at once. The Amulet is obviously good for that, but an Attack of Opportunity is also a good position-based reaction that could benefit from this.

I also went with Dread Martial stance since it seems like an action-economy saver (essentially free action intimidates every time someone crits), and there is some nice action-economy tied in with the Intimidate skill (Battle Cry).

The other feats I have planned are Snap Out Of It! and To Battle!, though both of those compete with the already action-heavy Thaumaturge, so they're more things that are nice to have than things I'll be using every round.
