The New Legend Rule is GOOD!
I suspect that with Champions of Kamigawa, Wizards will revolutionize the way they design Legends. Being a Legend is an inherent enough drawback to warrant ramping up the power level. Not only do you run the risk of”dead” draws by drawing multiple copies of the Legend, but now the Legend is vulnerable to a unique form of removal: a copy of itself played by your opponent. With Champions, if you’re willing to run the deckbuilding risks, you can be rewarded with great power.
