If a GM allows you to take Inquisitions on Druids that aren't
Nature Priests, that works. You can also play a plain old Inquisitor or play a
Sacred Servant Paladin worshiping
Ragathiel for the Rage subdomain or Anger inquisition. If you're going Anger inquisition on a character, I recommend dipping 1 level of
Ulfen Guard to obtain a rage power (Barbarian level stacks with your domain power rage), qualifying you for the
Extra Rage Power feat as well.
Also, using
Runic Charge + Pounce is quite clever. Now, a plain
Druid that's wildshaped into a pouncing shape can just Runic Charge with
Natural Spell. Alternatively, any psychic spellcaster could Runic Charge while polymorphed, but to get
Beast Shape II as a psychic spellcaster, you are typically either playing a
Material Manipulator Mesmerist, a
Psychic with the
Rebirth discipline (using Mnemonic Esoterica), using the
Samsaran's Mystic Past Life alternate racial trait to have been a Material Manipulator Mesmerist in your previous life, dipping a level of
Loremaster (probably on Psychic) and spamming
Secret of Magical Discipline feats (ideally your int should be high enough you can immediately obtain Secret of Magical Discipline as a bonus feat on Loremaster 1), just casting
Limited Wish for a polymorph of your choosing, playing a
Medium using the Archmage spirit to give yourself the Beast Shape or Monstrous Physique spell you desire while otherwise casting psychic spells, or playing a Sorcerer (or
Blood Arcanist) with the
Psychic bloodline (perhaps mixing it with
Crossblooded to also obtain the
Draconic bloodline of the Esoteric variant if you want to be able to Paragon Surge for all the spells on the Psychic spell list and swap out your 1st level bloodline power for a
Bloodline Familiar), which will handily afford you access to all the polymorphing spells. It is also possible to spellcast while in beast shape as a divine or arcane spellcaster by using
Grasping Tail +
Mischievous Tail and casting
Beastspeak (usually a stunt done by Shamans or Witches, but can also be done by
Spell Sage Wizards and of course anyone with the
Loremaster prestige class for
Secret of Magical Discipline or using
Samsaran Mystic Past Life). That will let you use verbal components and use your tail as a hand to fulfill somatic components. And you can obtain Beast Shape II and higher on any character by taking
Fey Obedience (
The Lantern King), perhaps using the
Evangelist prestige class for faster advancement, and using
Polymorph Any Object to
Greater Polymorph yourself (or someone else) with what is almost certain to be a +7 duration factor (animal kingdom, same intelligence or lower) or higher (if you are turning into a mammal or a creature same size as you), at which point you have permanent duration.
Alternatively, the
Skald can easily obtain pounce at a high level just by using Raging Song to give himself and any allies
Greater Beast Totem. He is also capable of using Spell Kenning to cast
Beast Shape II+ and
Beastspeak (using
Expanded Spell Kenning,
Runes of the Crone, or
Runes of the Old Faith).
In addition, you can obtain Pounce on any character by playing a
Catfolk with the
Claw Pounce feat and equipping
Claw Blades so you can make manufactured weapon attacks with your catfolk claws for iteratives, but you will want 10 BAB, so you'll want to raise your BAB perhaps or just take it at level 13 if you are a 3/4 BAB class. Cleric into
Holy Vindicator or
Scar Seeker (perhaps dipping a level of a full BAB class at 5)? Cleric/Shaman 4 + Ranger 1 into
Skyseeker? Wizard 4 + Fighter 1 into
Eldritch Knight? Psychic 6 +
Stargazer 3 into
Esoteric Knight (Claw Pounce at 14)? Just get ready to take
Prestigious Spellcaster feats if you go down that route.
You can also sort of imitate Spell Combat by using lesser metamagic rods of
Quicken Spell, or using the
Conductive or
Spell Storing property on your melee weapon. That reminds me, there is a trick with the Magus where you use
Quick Draw and keep drawing and using more spell storing weapons (dropping the previous one as a free action) to do a ridiculous amount of bonus attacks as each touch spell grants you another attack. Since the stored spell's touch attack does not, strictly speaking, need to be performed with the spell-storing weapon, it is perhaps possible to obtain as many bonus attacks as you have spell storing weapons on hand (which can get massive at high levels).
Lastly, the
Ectoplasmatist Spiritualist has his own version of spell combat, but unless your GM generously lifts the "can only attack with one hand" requirement which makes no sense for a Spiritualist and undermines a lot of the Ectoplasmatist's perks while leaving it mostly as a rather inferior Magus (who at least benefits from Arcane Pool, arcana, and bonus feats), it isn't particularly worth using.
