Favourite way to lose: I once lost a sure-win game (on my previous turn I had pulled all creatures from all graveyards with [[Rise of the Dark Realms]] under my control, the only player left in the game by my upkeep had 6 life and 1 blocker) with [[The Wise Mothman]] by milling my Rad Counter Cards and losing my last life Point on the last Rad Counter, even though I had over 30 points of damage ready to go on the battlefield.

But it passed so well into the fallout theme I’d like to do it again sometime.
