Pathfinder 1E Best summoner spells (4th level in my concentration) considering the wild arcana mythic ability

I know I might get quicker responses at the Paizo boards, but since we have a thread here now about mythic, I thought I'd provide a place here to ask what others think are good 4th (or whatever) level spells you would take, considering the Wild Arcana archmage mythic path ability.

For those not in the know, Wild Arcana lets you spend 1 point of mythic power to cast ANY 1 arcane spell on your class list as a swift action, of appropriate level. I don't want to talk about how awesome or over powered anyone thinks that might be.

I'm interested in seeing how this affects your choices of what spells (specifically 4th level for my character) you might choose. Or does it even affect your choices?

I'm thinking lesser planar binding might be something you would ordinarily pick, but with wild arcana it would be more useful to pick up teleport, or something you will cast repeatedly.

Same goes for summon monsters spells (not the summoners SLA).

Maybe Major Creation or Magic Jar?

Planar ally lets you save time, but is still costly. However, if you are suitably good-aligned, most good outsiders ought not to balk at assisting. I still am a bit doubtful about the combat utility tough, and combat is where time is critical. I'd pass on this.

Summon spells are a much better option. They arrive and act immediately, and you can position them at range to provide flank and threaten AoOs. Seems like a big win. Same goes for a bunch of other full-round spells like dominate, antipathy, deep slumber, geas.

A bunch of divination spells take time to cast, but not really worth speeding that up. In a crisis, it might matter.

Some trap spells might be worth it for general usage: symbol, guards & wards, forbidance. These could be quite handy with fast casting, but the spell slot devoted to them are a bit of a waste.

In the case of summoning spells and summoners that's less attractive thanks to the spell-like ability to summon things. But something I've noticed is the buffing spells could be useful to the whole party and communal stoneskin has an interesting difference from the regular spell.

Communal Stoneskin's material component costs less than the regular version. It's cheaper for 1 or 2 people using communal stoneskin than 1 person to use the regular version.
