Abzan Banner

The wedge banner that fixes three colors and, when the early game is over and the mana is no longer scarce, eats itself for a card. That second mode explains why this slot exists at all: rocks that only ever tap for mana go dead in the late game, so each clan banner builds in a release valve, trading itself for a draw once the colored pips it needs (one of each in its wedge) are trivial to assemble. It is a deliberately back-loaded design. The activation cost asks for exactly the three colors the artifact already produces, which means the card you sacrifice has spent the whole game proving you can pay to crack it. As a fixer it is plain three-color rock work, slower than a dual land and a turn behind the premium accelerants. Its argument is the one rocks rarely make: that it will not be a topdeck you regret. The lineage runs back through the diamond cycle and forward into every "mana rock that cashes out for a card" since; what dates this particular version is the rate, three mana for fixing that arrives a turn late and a sacrifice ability priced at full wedge cost rather than a single generic mana. Honest, unexciting, and built for decks that would rather not draw a dead rock on turn ten.
