Tyvar's Stand

Green protection spells have historically been fixed-purpose: Blossoming Defense, Ranger's Guile, and the old bear-heavy tricks save the creature and then do nothing else. This one refuses that ceiling. Because the same variable mana that buys hexproof and indestructible also buys raw stats, the spell reads differently at every point on the curve. Sink a single green into it early and it plays like a cheap Vines of Vastwood-style save; pour six or seven mana into it with a threat on the board and it becomes a lethal pump the opponent cannot answer. What makes the double layer of protection so complete is that hexproof and indestructible each shut off a different removal category: hexproof denies targeted spells and combat tricks, indestructible denies board wipes and unfavorable blocks. Stacking both on one creature means a single instant simultaneously beats a spot-removal spell, a Wrath, and a chump-block-and-trade, while the pump adds damage the opponent has no clean way to soak. Pump and protection normally live on separate design axes, one purely offensive and one purely defensive; folding both into a single scaling instant lets the card become whichever tool the moment calls for, defense when the creature is small and offense when the mana is deep.
