Vivi's Persistence

A pinger you cast rather than one you commit to the board. The token itself is fragile: a 0/1 that dies to almost any incidental damage, so the value lives entirely in how cheaply the spell comes back. This is a two-mana instant that reloads off your commander's routine, and every commander attack or reentry offers an optional rebuy, returning the card from your graveyard to your hand and letting you convert one token into a resource you keep recasting. It rewards decks already churning through noncreature spells, since each noncreature spell you cast turns the Wizard into a one-sided damage source against the whole table: the token hits each opponent for 1 and never touches your own life total. The math is straightforward spellslinger arithmetic: against three opponents, one cheap cantrip is three damage, and a busy turn compounds quickly, all without asking anything of your attackers or your mana beyond the spells you were casting anyway. The recursion clause is what keeps the engine from spinning freely. The spell only comes back when your commander enters or attacks, and only if you pay, so the loop is tethered to keeping a commander alive and swinging rather than to a free sacrifice-and-recur package. That tether is the balancing act: the card punishes wide, spell-heavy tables that leave the pinger unanswered, yet stays quiet in decks that do not lean on the noncreature count and cannot reliably fire the rebuy.
