Voltron decks (not to be confused with Tron itself) concentrate Auras, Equipment, counters, and protection onto one creature until it becomes capable of winning combat almost single-handedly. In Commander, that creature is usually the commander itself.
Uril, the Miststalker rewards loading up on Auras, while Sram, Senior Edificer draws cards from Aura and Equipment spells. Double strike, evasion, and protection help convert one enormous creature into lethal commander damage.
