Forum:Using more than one Heart of the underdog

When Heart of the underdog is on the field, and you draw a normal monster during your draw phase you can draw again, and you can keep drawing if you keep getting normal monsters (by showing the normal monster to your opponent.) If you have two heart of the underdogs on the field and you draw a normal monster you can draw two cards by showing the card you drew to your opponent. If you were to draw one card that wasn't a normal monster and one that is would you just draw again for just the one card? And if you drew two normal monsters would you draw two more cards for each other them? For instance I had two Heart of the underdogs on the field and I drew a normal monster, and then I drew two cards for drawing a normal monster. The two cards I drew were both normal monsters so I drew two cards each for them (four cards). I received three normal monsters and one magic card, so I drew two cards for each normal monster (six cards). This kept going until I drew my whole deck and got all the pieces of exodia. Am I using this card correctly?
