Zilean + GP Dreadway Timebombs

The wackiest idea I've had all day, but hear me out! Smooth Soloist reduce mana costs which is clutch for L2 Zilean, and Dreadway obviously doubles the value of each bomb. Plus all the bombs are amazing plunder activators. The only thing: I hope they special-coded kegs to detonate timebombs, because the kegs otherwise don't have a lot of synergies.
