This one is really nice. I played a lot of wizards using familiars (using them, not just having them) and it's always a whole lot of fun. Enspell Familiar is my favorite feat, it grants huge utility and is really mighty, especially at level 5+
Last wizard, I had a Lantern Archon PAOed into an Eladrin (RP-reasons), he had his Feat Chaos-Reshuffled into something else (I think it was Martial Study). He had Maze 1/day by the Epic Feat Familiar Spell and some lower-level-spells by that Imbue Familiar with Spell Ability spell, also he had tons of utility equipment, especially debuff-counter-consumables like Potions and scrolls. He had Superior Resistance, Moment of Prescience, Greater Mage Armor, the Heart of... spells, Foresight, Dragonskin... He also had some Teleportation options, which is really powerful.
Celerity + Used on Familiar + Teleportation from Familiar or Wall cast by Familiar is a not-so-cheesy use of Celerity, that doesn't make you dazed (it just dazes your familiar).
Or you share the Celerity (so you gain the bonus action yourself) and then use Time Stop (and you can share that, too).
/edit: on your Spell-Linked Familiar note: I once played a metamagic rogue 1/wiz X/unseen seer with ECL 9-12, I had a raven back then and I had spell-linked familiar for one simple reason: Even though IFwSA (imbue familiar...) is much better, I never had enough firing power to really last through the day, so the additional Rays helped. I use spells like Acid Splash combined with a shared CL-buffed Hunter's Eye (ranger spell via Unseen Seer added to wiz list that grants +1d6 SA per 3 CL) for damage with attacks against the flat-footed touch AC of my enemies.
