Karlov is a 2-mana commander that snowballs by gaining life: every lifegain trigger adds two +1/+1 counters, growing him into a massive beater and fueling his exile ability. You build a lifegain engine, swing for commander damage, and repeatedly exile threats while padding your life total against the table.
Tighten the lifegain density with cheap repeatable triggers (Soul Warden effects, Bloodthirsty Blade, Children of Korlis) and add a clean combo line via Exquisite Blood + Sanguine Bond/Vito. Improve protection with Swiftfoot Boots, Lightning Greaves, and Teferi's Protection, plus fast mana like Sol Ring and signets to land Karlov early. Add counter-doublers (Cathars' Crusade, Hardened Scales, Branching Evolution) to make his exile ability and clock far more explosive.
