The attack trigger reads like an edict pointed at both players at once, but the real payload is buried in the last clause: every land that hits a graveyard through the discard-or-sacrifice choice replaces itself with a card. That turns a symmetrical Smallpox-style resource strip into an engine that runs asymmetrically in your favor if you can keep feeding lands to the trigger, whether from your own hand or by pressuring an opponent light on nonland permanents. It is a card built to reward a graveyard-and-lands shell rather than a stax deck: the more expendable lands in the game, the more the attack refills you. Encore is the second gear, and a steep one at eight mana. Exiling from the graveyard for a token copy per opponent means the body's attack trigger fires against each of them separately, multiplying the discard-or-sacrifice edicts around the table in a single sorcery-speed swing before the copies sacrifice themselves at end of turn. The line asks you to first get the 4/4 into the yard, which the card's own attacks help arrange, then spend a full turn's worth of mana to detonate it as a table-wide resource assault. Two distinct clocks, then: a grindy attrition body in the early game and a one-shot multiplayer edict later, with the land-draw clause stitching both to a deck that treats its own graveyard as a stockpile.
