I was down to 1hp, against an FG and he was owning me badly. Lots of low HP creatures though, luckily, I had no creatures, was staying alive because of a phase shield, had my hourglass and 2 empathetic bonds on the field and two boneyards. I drew a firestorm, played bonewall, wiped out his field, got an almost full field of skellies and a big bonewall. Ended up winning the game with Element Mastery. Though, that happens rather frequently to me.
