If you have {Melek, Izzet Paragon} and  {Galvanoth} out at the same time,
you get the top card of your library cast and copied for free before you draw.

Add {Pyromancer Ascension} and you'll get three instances!
And throw in a {Nivmagus Elemental}, you can have him grow by exiling unwanted copies or dead spells!

 {Reverberate} a {Increasing Vengeance} cast from a graveyard. Make the copy copy the copy, making infinite copies.

This works because Increasing Vengeance from the graceyard makes TWO copies per resolution, instead of Reverberate's only one.

Now have {Nivmagus Elemental} eat off the infinite copy loop, becoming an infinitely large creature.
