Whenever Jecht deals combat damage to a player, you may exile it, then return it to the battlefield transformed under its owner's control.
(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I, II — Jecht Beam — Each opponent discards a card and you draw a card.
III — Ultimate Jecht Shot — Each opponent sacrifices two creatures of their choice.
Menace
Jecht is a 4-mana mono-black evasive beater that flips into a Saga the moment he connects, turning combat damage into card advantage and a forced double-sacrifice edict. You attack early with menace, transform him to strip hands and remove blockers, then sacrifice the Saga and recast him to do it all again as a recurring attrition engine.
Repeatable hand disruption and forced sacrifice that grinds out the table
Cheap 4-mana commander that's easy to cast and re-cast as the Saga sacrifices itself
Menace makes him hard to block, reliably triggering the transform
Mono-black gives deep access to tutors, recursion, and removal to support an attrition plan
Needs to connect in combat to transform, so single-target removal or chump-proof boards stall the engine
Edict effects miss decks with token fodder or a single must-keep creature
Mono-black lacks card draw outside life payment and struggles with enchantment/artifact removal
Slow against fast combo decks that ignore the grind
