Assuming you mean Keeper of the Flame (a red Human Wizard from the Portal set with Whenever Keeper of the Flame attacks, it deals 2 damage to any target), here are similar mono-red cards:
1. Chandra, Fire of Kaladesh – Pings opponents/creatures when you cast red spells; flips to a planeswalker.
2. Thermo-Alchemist – Taps to deal 1 damage to each opponent; untaps with instants/sorceries.
3. Ash Zealot – Has first strike and deals 3 damage if an opponent casts a card from a graveyard.
4. Viashino Pyromancer – Deals 2 damage to target player/planeswalker when entering the battlefield.
5. Ember Hauler – Can sacrifice itself to deal 2 damage to any target.
Reason: All are red creatures with triggered or activated abilities that deal direct damage.
