Tom LaPille, When Cards Go Bad, Part 2, a followup to the first When Good Cards Go Bad article thesunneversets linked, has a few more points that haven't been fully explored yet.

Some cards aren't fun when they're good.

Here he uses the example of Scrambleverse, which has really cumbersome and complicated mechanics, explaining that it is costed very high so that it doesn't get played often. The only people that play it are the people that really want to.

Limited needs to be balanced.

I think Limited play is the biggest reason there are "bad" cards in modern MtG. From the article:


  …there was a meeting when both blue and black were doing much better than we wanted in our playtests. Lead developer Aaron Forsythe decreed that we needed a weak blue card and a weak black card. None of us came up with a blue card that was weak enough, so Aaron created Defensive Stance to fill the hole.


So while Defensive Stance does have some narrow infect-hosing mechanic, it was basically created just to keep blue drafters in New Phyrexia in check.

Draft needs to be human-processable.


  Drafting is a complex enough task already without every card being extremely close together in power, so we include plenty of cards of widely differing power levels so that the right answer can be a little bit less ambiguous. This doesn't simplify the task of correctly identifying those power levels—a challenging task in itself!—but it does make deciding between correctly-identified power levels a little bit easier.


Imagine if every card in a pack had the same power-level. I have a hard enough time deciding between two or three similar power-level cards in a draft. If all cards had a similar power level, each decision becomes stressful and agonizing. Drafts would slow to a crawl. If there are some "last pick" cards and definite common "bombs", it makes the draft a bit more smooth and manageable.  

Why does Wizards of the Coast print terrible MTG cards?
Been having some bottom bracket (BB) woes. Noticed a click on the top of the left pedal stroke decided to re-grease the BB. Took it apart cleaned everything re-greased, put it back together. 
Roll forward a week.
Notice my cranks sticking here and there, gets progressively worse on the ride. Get it home and off the bike notice my bike has turned into a rain-stick (this provided no calming effect)
Que another strip down of the BB.
Upon inspection, I found all the bearing on the non lockring side of the where out of the cage, which now would no longer hold them. I pinched the cages with pilers to secure the ball bearings back in place. Re-greased repacked.
Lifted my bike out today for my cycle to work jingle-jingle; LOOSE BEARING!
Cycle to work was sub 3miles so risked it.
Want to take care of this ASAP, so my questions are:

1. I figure I am over-tighting the bottom bracket, causing the damage to the cage, however what else could cause?

BB info:


Campagnolo Italian threaded
plastic sleeve is in two parts, the smaller part pushes into the
other.
2 caged bearings from memory 8/9 bearings in each cage.
Two screw in cones one locking.


here is a pics of my spindle:


Brev whatever that means


2. What size bearing does an Italian threaded BB take?
