Forum:Multiple heart of the underdog

My question pertains to a previous question on the forums. What would happen if say you have three heart of the underdogs out. You draw a normal monster and then get to draw three cards. you draw 2 normal monsters and one spell card. would you still be able to draw two more cards but not the third because one was with a spell card? I'm assuming that you can continue picking as long as you get normal monsters. sorry I'm still kind of new at this. also for future referance what is the 4 tildes? just the squwiglly line thing? Thanks for all the help. Coltman66
