A different spin on my Bard build up thread:
Minotaur, Lion's Pounce Barbarian 1, Fighter 2, Warhulk 10
Key feats:
Quickdraw
Improved Initiative
Versatile (Add Spellcraft and UMD to all class lists)
Destructive Rage
Key Magic Items:
Anti-Magic Torque
Scrolls of Celerity, Greater Celerity, Moment of Prescience, Sign
Anything else that buffs initiative
The trick is to ready an action to use a scroll to counter spell. The Minotaur causes the Wizard's Foresight to activate, the Wizard casts Celerity (possibly Greater Celerity), the Minotaur quickdraws the appropriate scroll and counterspells. Lets say the Minotaur has optimized his initiative enough to win initiative, as a free action he uses his AMF. The Hat drops, the Wizard doesn't have another swift/immediate action to use when the Hat comes down, the Minotaur rages and makes the strength check to punch a hole in the cone, letting the AMF in.
The Minotaur can also pick up the cone as a light load, I'm sure you could do something funny with that.
You could do basically the same trick with a Fighter 20, if you can make a build that can do 120+ points as a standard action (maybe as a full attack if you start closer to the Wizard).
