Fun late game midrange big creature and big spells deck. Would not consider it competitive tho.

You wanna ramp with mana artefacts and tribal mana cost cheating cards to get them big giants/angels/avatars out while kalemne is out so she exponantially scales. Even a +3 XP counter Kalemne gets out of hand quick and win con is your cmdr dmg. There is some permanents interractions but mostly it is instant, on cast, big impact effects and strategy revolves around kalemne scaling and attacking.

It is really slow and lack of draw pot makes it easily very painful early, if mana screwed or if you fall behind on tempo/card adv. Hence, it also struggles vs control (removal and counterspells) that will deny your big effects and screw up your mana budget and tempo (most turns = 1 or 2 casts). However, if you can ramp, get ignored early game (which will happen a lot vs faster decks) or get matched againts other creature decks, each cast is high impact, snowbally and you will creep back / drop some jaws.
