Bastion Inventor (AER)

Creature — Vedalken Artificer

Improvise (Your artifacts can help cast this spell. Each artifact you tap after you're done activating mana abilities pays for {1}.) Hexproof (This creature can't be the target of spells or abilities your opponents control.)

Solid hexproof creature for artifact-heavy Commander and Pioneer decks. Bastion Inventor rewards you for playing artifacts by reducing its effective cost through improvise while providing evasion that's genuinely hard to remove. The six-mana floor is steep, but in decks already built around artifact synergies—Breya, Urza, or artifact-focused control shells—it becomes a resilient threat that dodges targeted removal and board wipes alike.
