An early (1999) Pro Tour combo
{Enduring Renewal} + {Goblin Bombardment} + {Shield Sphere}
Sac the Shield to the bombardment for 1 point of damage, Enduring Renewal brings it back to your hand. Go Arbitrarily Large!
Now, if you look back at Kai Budde's version, he had access to gems like {Force of Will}, {Brainstorm}, {Impulse}, and Dualies. Man, those were the days!

This is funny, and not to mention the cards mana costs are very low. I could make a deck arround this idea!!
Nice budget combo, I approve
