Furystoke Giant

The 3/3 that comes back once is filler; what the card sells is a board-wide pinger, handing every other creature you control a one-shot Prodigal Sorcerer activation for the turn, except each tap deals two damage rather than one. The math compounds with width. Five other creatures means ten points of redistributable damage the moment it lands, enough to sweep a board of small bodies, finish a planeswalker, or just point the whole battery at a face. Persist is the wrinkle that turns the spike into an engine. Because the enters-the-battlefield trigger fires every time it arrives, killing the Giant and letting it return reloads the gun: a second wave of "tap for 2 damage" the following turn, off the same card. That is the line designers were clearly playing toward, pairing a death-recursion keyword with a re-triggering ETB so the two mechanics feed each other instead of sitting side by side. Note what stays disciplined: the granted ability requires tapping, so the damage is gated by summoning sickness and by how many untapped attackers you are willing to leave home. You are choosing between swinging and shooting, not getting both for free. It rewards a go-wide red board far more than it ever rewards a fair midrange curve, unremarkable until the table is full of creatures and suddenly every one of them is a Shock on legs.
