Summon: Titan

The front-loaded value here is not the chapters; it is the 7/7 with reach and trample that shows up the moment the Saga hits, a body that keeps the card relevant on an empty board while the lore counters tick. What the chapters add is a self-contained ramp loop. Chapter I mills five, which reads as a cost until chapter II reads it as fuel: every land buried in that mill (plus anything a fetch or a sacrifice put there earlier) returns tapped, turning the graveyard into a reservoir of extra mana. Mass land recursion is green's home turf, so the effect itself is idiomatic; what makes the sequencing sing is that the mill feeds the reanimation directly, so the two chapters function as one engine rather than two unrelated triggers. Chapter III then cashes the accumulated board out, handing another creature trample and a pump equal to your land count, a number the recursion has been inflating for two turns. The trample it grants matters precisely because the recipient may not have had it: this is the chapter that turns a wide-but-grounded board into a lethal swing. Sacrifice after III keeps it honest. The engine is a three-turn burst that consumes itself, not a permanent ramp fixture, which is what stops a chapter that can double your effective mana and dump it onto one creature from becoming a runaway loop.
