Quote from WizardMN »I might be in the minority here, but I *do* prefer shuffling 100 cards (and I double sleeve mine and I have "normal" sized hands). Whenever I shuffle a 60 card deck, it just feels like I have nothing in hand. I have no problems with the shuffling after every search and I have no problems shuffling the deck in general.Quote from Magic2020 »
b) Shuffling 100 cards isn't fun. And that is why most play the game, for fun. Do you really enjoy shuffling 100 cards? While its possible to build a fetching/tutoring deck, is it really fun to shuffle 100 cards every turn?
c) It costs more. I love to spend money, heck who doesn't. But who really likes to find and then spend hundreds (or even thousands) to test a new possible mechanic or to build a top competitive 100 card commander deck?
d) It can force you to add subpar or weak cards. Having 100 cards can sometimes force you to add weak cards for that mechanic simply to fulfill the 100 card requirement. Do you really like to add and then draw weak cards?
These two things are at odds with one another. It can't cost more *and* force subpar cards. At least, they can't both be used as generalities. In any case, I disagree with point 'd' (I don't really agree with point 'c' either but I have a feeling that is more subjective). There are 20,000+ cards in Magic. If you are running subpar cards either you didn't look hard enough or you think anything worse than Cyclonic Rift or Sol Ring is subpar. They may be "worse" but there are plenty of good cards you can include in decks.
What I mean by this is that if each deck has 80 high quality cards, adding an additional 20 subpar cards to meet 100 cards will increase the cost. You have to buy the 80 quality cards, and then spend additional money buying subpar cards. This is one reason why I support smaller decks: less cost.
Deck A = 80 cards: 80 high quality cards ($2 each or $160) = $160 total
Deck B = 100 cards: 80 high quality cards same as above ($160) + 20 subpar cards ($1 each) = $180 total
