Whats a Magus to do with the various Polymorph spells

[Katana1515]

Starting a new game with a lvl 14 Magus, and was wondering if the wise minds here could suggest some use for the various PF polymorph style spells that are on the spell list. The Spells are very flexible and I am sure that you guys can suggest some amazing forms that I would never think of. Some Utility/Stealth forms would be interesting as well as any notable forms for fighting.

Buildwise, its a Strength Magus with a Scimitar (inevitably XD) and heavy armour. Filling in a DPS and possibly the scout role in the party.

Additional note! This is a 3.P game so anything fun from 3.5 books would be more than welcome.

Will link the spells in question for those unfamiliar but interested.

Use monstrous physique to transform into a hybrid form weretiger, buff with haste then pounce on your targets for massive damage.

As long as you ignore the silly FAQ ruling, you can also spellstrike on your pounce.

Monstrous physique 2 = doppelganger's mimicry ability = proficiency with all exotic weapons + activate all scrolls and wands from any class without UMD check.

The monstrous physique shape line also sports the tikbalang, from Bestiary 4 I believe, which sports the excellent Pounce ability.

[Abd al-Azrad]

The Calikang, from the Inner Seas Campaign Setting, is a large foe with six arms, six slam attacks and a beefy breath weapon. While it does not give you Pounce, using Spell Combat to slip a Frostbite into its natural attack routine will allow you to use your Scimitar and five secondary natural attacks, each of which adds your level to damage.

I would consider that pretty terrifying.
