I play a fast white deck with a little green. My reasoning?
74% of people think that blue is the strongest colour. The best defence against a control deck is a speed deck, usually white or green.

Yay for MTG.

Only for america and canada? dam, that sucks.

I suppose that the gems crack when they are put under too much strain, not because the stormlight inside them was transferred. They similarly are known for cracking when repairing shardplate. The gems, which are like a tool, are being overworked.
When people breathe in the stormlight from the gems, the people are put under the strain, and not the gems. This is why no gems have ever cracked by having their stormlight sucked. It also explains why the more stormlight you use, when it is depleted, the more tired you feel.
