Masked Vandal can exile a creature from our graveyard to exile Bonder's Ornament or Expedition Map, disrupting Tron's mana acceleration and card selection package, though it cannot touch Urza's Tower/Mine/Power Plant since they are not artifacts or enchantments. Since this is a grindy ramp mirror, our best plan is simply to out-ramp and out-size them with our own big mana into Generous Ent, Bramble Wurm-tier threats via Winding Way and Lead the Stampede. Trim the weaker mana dorks that don't scale as well since we want bodies that also apply pressure. This matchup comes down to who assembles their payoffs first, so keep the core engine (Axebane Guardian, Overgrown Battlement, Priest of Titania) fully intact.
