RE: Nidhoggr Adjustment Proposal: Addressing Airdrop Balance and Improving Tactics

I could get on board with a few varieties of the card going back to the drawing board and being made available for widespread testing. I think this actually presents a great opportunity to put Ghost Card challenges to the test of this use-case.

However, I'll ultimately default to @ajpl @nameless-112 for their insight as far as what expectations / requests the proposal puts forth.
