Build Advice for Master summoner

[JuliusCromwell]

Ok so my Swashbuckler met a messy end and I have picked a summoner as my next build.

My plan is to have a plethora of creatures at my command.

So I'm starting with 7 levels of unchained Master summoner
Question (should I stack another Archetype?)

My feats Are
Feats
1: Spell Focus (Conjur)
2: Augment Summoning
3: Superior summons
4 Versatile summon monster
5: Vampric summoning (lv5)
6: Extra summon monster

(Gm is giving us all 2 bonus feats to start)

For the feats is there anything I should change.

For my Eldolion I am planing on an angel build
But not sure were to take it

I like these guides:
Summoners - Specialist Sorcerors with a party of their own
Why work when others can do it for you - a guide to Monster Summoning
Summoning Information - a guide to an alternate Eidolon (using edidolon as guide)

do not forget to change to READ ONLY in right upper corner

I am building my own (not unchained – unchained is bit nerfed) using variant multiclassing into bard so that he can also buff (inspire courage) his minions and has reliable knowledge about enemies.

I can also share my spreadsheet with spells, spell like abilities and effect of summoned creatures.
