Ways to buff summoned monsters

[ZᴇɴN]

I'm looking for ways for a summoner to have reliable/always on buffs for their summoned monsters (ideally, PFS legal).

What I've got so far is:

Augment Summoning

Flagbearer

Suzerain Sceptre

Battle Cry

Wysp familiar + Versatile Summon Monster

Anybody got any other suggestions? Preferably that don't require dipping.

Rod of Giant Summoning with Augment Summoning is very strong.

Evolved summon monster, summon good monster, leadership for a bard/skald cohort.

Evolved Summon Monster is really good if you get to pick from the APG list rather than Unchained, and isn't PFS legal anyway. Summon Good Monster is fine but not good until higher levels.

Leadership for a Bard buddy would be fantastic, so would VMC Bard. I would love to be able to use VMC in PFS. Leadership basically nobody ever allows, and rightly so.

Along those lines, though, binding one of the outsiders with Bardic Performance would be cool.

Flagbearer can be augmented by magical banners - for example, Banner of the Ancient Kings.
