Monastery Siege

The modal enchantment cycle named for warring factions gave each color a choose-on-entry split, and blue's pair captures the two poses the color is most comfortable in: digging and stonewalling. The Khans mode turns every draw step into a loot, a slow card-selection engine that smooths draws and feeds the graveyard without committing you to a single plan. The Dragons mode is the more pointed half, taxing any spell an opponent aims at you or your stuff by two: not a hard counter, but a Sphere of Resistance pointed only at interaction, the kind of friction that makes a combo turn or a protected threat much harder to break up. What gives the card its longevity is that the choice is locked at entry, so the same three-mana enchantment serves a controlling deck wanting fuel and a defensive deck wanting a soft shield, and you pick which problem you have when you cast it. The Khans side is the one that has aged into a quiet staple: a recurring, repeatable selection effect that asks nothing of the board and never stops working, which is exactly the profile that survives across formats. The Dragons side stays niche by design, a tax that only bites when opponents are spending mana to attack your position, but in the right matchup it taxes precisely the spells you least want to resolve.
