Have you guys tried to use a normal monster deck with Heart of the Underdog even with Igknights and stuff? It's pretty hard. It either gets destroyed before you get value out of it or you don't draw a normal monster. Kinda sucks.

I have actually, using HotU in a normal pendulum monster deck, I ended up drawing like 10 cards.
