lvl 12 PVP (1on1)

[JohnStone]

im looking to utilize animal companions in a pvp (1on1) Pathfinder game.
LVL 12, 25 point buy
its been said that skills and charisma could be useful...
there will be large island arenas, with time to buff, hide,or stalk/track the other combatant.
NO FLYING

PACK HUNTING
im looking at druid (pack lord)
Ranger(beastmaster)
or possibly Cavalier(Huntsman).

MOUNT
A different approach, but im looking at cavalier(beastrider)(T-REX)
or possibly the mounted Archery Ranger using a wolf or T-Rex

any opinions would be appreciated (I like the idea of pack hunting, but I also want to win)

Consider an Aasimar Lunar Oracle, see how the other guy likes facing a lvl 18 celestial wolf companion, especially if you spend a chunk of gold getting a pack of dire wolves (20+ probably, 380 gp each, CR 3) that your animal companion can talk to (Totem Guide archetype for the companion)/influence (it is clearly the Pack Leader).

4+ int skills, d8 HD, dump dex and take the Cha to AC/Ref mystery for good defense, cast spells all day long with your Full-1 casting and money for wands.

For the water just to buy a Folding Boat for you and your pack. Have your animal companion take Profession (sailor) for driving the ship and bonus points ("Welcome to port captain... Scuffles?")

If you want to be mounted you still can, completely ignoring the ride skill as you buy an Equestrian Belt that grants auto-successes while in less than heavy armor

Don't forget to take Scion of Humanity, Racial Heritage (Half-Elf), Skill Focus (Any knowledge), and Eldritch Knowledge Arcane. If you do this you'll have access to both the entire Cleric/Oracle and Sorcerer/Wizard list with Paragon Surge, gaining access to Expanded Arcana/Improved Eldritch Heritage respectively. You have 6th levels spells so should be no problem.
