Speedball, New Warrior - Legendary Pauper Commander

Zero-Cost Redirection: Its ability is an on-cast trigger with no mana cost. It completely flips tempo: every opposing spot removal turns into an asymmetric 2-for-1 in favor of the Speedball player.
Collapse of Removal Spells: The format relies heavily on a wide variety of interactions, many of which are single-target (Cast Down, Lightning Bolt, etc.) due to the scarcity of efficient common board wipes. Speedball renders spot removal completely useless, becoming a rogue threat regardless of the deck it faces.
Unlimited Voltron Engine: With no trigger limits per turn, it serves as both free protection and a permanent stat buff with every interaction. Consequently, any burn spell or targeted effect effectively adds “+2/+2” to the commander.
Overly Specific Answers: It is only kept in check by extremely specific answers such as edict effects, counterspells, or enchantments that exile upon entering the battlefield. This makes it overwhelmingly powerful in too many matchups.
