Rain of Rust

Entwine is the mechanic that asks you to pay for flexibility twice, and the pricing here is the entire negotiation. At the base rate you are paying a real premium over the era's dedicated answers, since both artifact removal and land destruction came cheaper in their single-purpose forms. What the cost buys instead is optionality without commitment: the same card kills a problem artifact one turn and strands an opponent on a key land another, and against the right two-permanent pressure point the entwine surcharge folds both modes into a single instant-speed two-for-one. That instant speed is the quiet structural advantage. Most land destruction of this school was sorcery-locked, so holding up the choice (or both choices) until an opponent commits gives this a reactive posture the Stone Rain lineage never had. The friction is the total mana: even when you split the difference and pay for both halves, you cross into a tempo loss that punishes greed. The whole design hinges on a single deferred decision, where the cost structure forces a choice between cheap-and-narrow now or expensive-and-complete later, and pays patience over reflex.
