The Flame of Keld
The genius of this Saga is that its weakness and its payoff are scheduled events rather than choices. Chapter I empties your hand: brutal for any deck that wants cards, trivial for the aggressive red deck that has already dumped its hand by turn three or four and would gladly trade a stray land for the refuel. Chapter II hands two cards back the next turn, so the deck that entered with one or zero cards in hand actually nets ahead. Then Chapter III adds two damage to every red source you control for one turn: a Shock deals four, a Lightning Bolt deals five, an attacker swings for two more, a sweeper cleans up the stragglers it left behind. The staging is what keeps it fair. A flat "your red sources deal +2 damage" enchantment at this cost would be absurd on rate alone, so the design forces you to eat the empty-hand setup and the delay before the multiplier ever comes online, and the Saga sacrifices itself the turn it pays off. The buff is a single decisive turn, not a permanent fixture. What it really converts is tempo into reach: it rewards the deck that wants to be hellbent anyway, the one that spends everything early, refuels mid-game, then points a hand of burn and a board of attackers at one suddenly two-bigger turn. The discard and the delay are the price of a closing turn few other cheap red cards can manufacture on schedule.
