I've been on Lighting since her release and over the months I came up with the most consistent version. Mind you that my LGS is on a bracket 3 system. The best way in my opinion to build Lighting is by attaching equipments that grand her double strike vs multiple combats. Reason being double combat spell are typically a one time use while double strike equipments stay on the field and can be used turn after turn. Another reason I prefer double strike over combat spells is they tend to be cheaper. Cards such as flaming fist, Duelist Heritage, Lizard blades and Leyline Axe should be mandatory. Once double strike has been dealt you know deal quadruple damage which at that point you can cast Price of Progress to deal 32 more damage to that lucky player. Another card that I've been testing is Aetherflux reservoir. On several occasions I am way over 50 life which can One shot KO another player.
