Of course this not to say "yugioh is better" I in fact love this game a lot more, Yugioh charges nothing due to it being an invite only event. However they do in fact have a much bigger budget to work with that while we cannot match it we can learn from it. I think sleeves, mats and card that say "top 128", top 64 tec will have a big impact. They used to produced them for pre-releases (at least sleeves and stamp promos). They will need to make only 128 of them. and then top 16 or 32 can get the mats.
