Started as an attempt to make a bad card good: Golem foundry. Turned out a lot better than I thought it would. Basically you need leyline in your opening hand, then stall with counterspells until you get a foundry out, hopefully on turn 3. Then, with pranksters in hand, pass turn 4 and at the end of turn flash in pranksters followed by a 0 cost artifact creature, then another returning the first to your hand. Repeat for infinite golems.
