I can't seem to find any rulings on this anywhere, and I know solemn wishes only activates once with Pot of Greed, or Graceful Charity for instance, but what if you draw a normal monster with Heart of the Underdog down? Would Solemn Wishes activate only the first time, or would it activate every time that you activate Heart of the Underdog's effect? Meaning basically if you got to draw 4 cards in one turn using HotU, would you just gain 500 LP or 2000 LP?
