[Yu-Gi-Oh] Why are the Egyptian God card considered such a big deal when Exodia (and some other cards) are instant wins, no fighting needed?

If the “heart of the cards” is on your side then Exodia is indeed unstoppable. But if you do not have the “heart of the cards” helping your draws then you need to rely on luck/deck build to get five separate and relatively weak cards into your hand at the same time. The rare hunter who had a deck with three sets of Exodia in it had great difficulty once Yugi learned his gimmick because his deck was weighed down by 15 Exodia cards and had little else going for it besides the ability to mill his own deck and stall somewhat. By contrast, the god cards are always useful if you can summon them and don’t require all that much more to make them work than any powerful monster. 

Also the god cards are actually connected to said Egyptian gods and have related supernatural effects, especially in the case of Ra which requires knowledge of Egyptian script to use and smites anyone who plays a counterfeit.
