Whenever you cast a creature spell with mana value 5 or greater, you get an experience counter.
Kalemne gets +1/+1 for each experience counter you have.
Cast big creatures (MV 5+) to rack up experience counters, growing Kalemne into a double-striking, vigilant beater that closes games fast. Ramp hard early, drop fatties to gain counters, and protect Kalemne with equipment and combat tricks so her doubled damage ends players quickly.
Double strike plus a growing power makes Kalemne lethal commander damage in just a couple swings
Vigilance lets her attack and still defend, controlling the board
Experience counters survive board wipes and Kalemne's removal, so she scales back up cheaply
Giants and big-creature synergies give access to powerful, splashy threats
Boros has excellent ramp, equipment, and protection support
Heavily commander-dependent; if Kalemne is repeatedly removed the deck stalls
Boros lacks card draw and ramp compared to other color pairs, leading to flood/screw issues
Casting only MV 5+ creatures for counters is slow and mana-intensive
Vulnerable to exile, edicts, and chump-blocking that blunt commander damage
Few interaction options compared to blue/black decks
