For most people, the main/important factors deciding an outcome of an event, or game in general would be based on the following three elements. 1/. Deck Choice. This basically includes play testing to come up with a list, deciding what to play - including metagaming with techs, or playing original rogues with a surprise factor. 2/. Player Skill. Although arugably has a huge impact on deck choice, this mainly refers to a players actual ability to play what cards they have in their hand/cards they have in play, based on the information they have (i.e. opponent's discard, cards in play etc) the most effectively for the situation. 3/. Luck. An element nearly enevitable in every card game (even if it is less significant in some games, any game that requires shuffle/draw, involves at least 'some' luck. With every format, that is older sets rotated out, newer sets introduced, and even new rulings on cards, can change how important of a deciding factor luck is in the format. My question to you is, in "today's format", in this case which I define as EX-Holon Phantoms - Diamond and Pearl 5: Majestic Dawns, including all erata/rulings imposed, how important is luck as a deciding factors, when juxtaposed, compared and contrasted?
