60-90, Where do you fall?

I used to always build 90 card decks and have cards in there for fun situations that may appear i.e Vulnerability, From a Sinking Ship etc...

However I now work on a 70-80 card limit and try to focus the deck on what its doing. It all depends on your style of play, whether its a group or tournament and what you want your deck to do. One good thing I have seen people do is to have 2 ash heaps - one for played cards and one for discarded cards. If you keep discarding the same card in every game then its better just to take it out.

I prefer to drop the 0s and lay down.

I tend to build 88 card decks, because I like big, approx. 90 card decks, sleeves are sold in packs of 50, and that way I can use two packs of sleeves to a) sleeve an entire library and b) use the remaining sleeves on the crypt for a 12 card crypt in a different deck (so I don't have library and crypt of the same deck sleeved in the same color, to avoid confusion)

As others have said, depending on what type of deck. Compat 90 other decks tend to land at 70-79 cards. Why dont know but it feels right and flows good...

I have a tendency to end up at 76, guess it depends on what decks you like to build.

I've built decks of about 80 cards lately. Even combat decks I build are about 80 cards.
