Human Torch, Johnny Storm is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Flying Whenever you draw a card, if you control another Hero, Human Torch deals 1 damage to target opponent. Power-up — : Put three +1/+1 counters on Human Torch. (Activate each power-up ability only once. Reduce the cost by his mana cost if he entered this turn.)

Complete guide

Ignite the battlefield with the hottest member of the Fantastic Four, Human Torch, Johnny Storm! This aggressive red creature rewards you for drawing cards while you have a team of heroes at your side. Whether you are pinging opponents or utilizing his massive Power-up ability, he is a fiery threat that demands an answer.

Fiery Synergy

Human Torch, Johnny Storm has a triggered ability that checks for two things: that you have drawn a card and that you control another Hero. If both conditions are met, he deals 1 damage to a target opponent. This makes him an excellent engine in decks that focus on card advantage and Hero synergies.

Understanding Power-up

The Power-up ability is a new mechanic that allows Johnny Storm to grow significantly in size. You can only activate this ability once per game. Crucially, if Human Torch entered the battlefield this turn, the cost of the Power-up is reduced by his mana cost, meaning you only pay {4} instead of {6}{R} to add those three +1/+1 counters.

Common Mistakes

Players often forget that the Hero check happens both when the ability triggers and when it resolves. If your only other Hero is removed in response to the draw trigger, the ability will not deal damage. Additionally, remember that the Power-up cost reduction only applies during the turn he enters the battlefield, regardless of how he entered.

Tactical Timing

To maximize the efficiency of Human Torch, Johnny Storm, try to save enough mana to activate Power-up the same turn he is cast. This makes him a 5/5 flyer immediately for a total of seven mana, rather than waiting a turn and paying nine. Use instant-speed draw spells to trigger his damage ability on your opponents' turns.

Interaction examples

Drawing Through Death

Solemn Simulacrum

If you control both creatures and Solemn Simulacrum dies, its triggered ability goes on the stack. When it resolves, you draw a card. Since Solemn Simulacrum is not a Hero, Human Torch's ability will only trigger if you control a different permanent with the Hero subtype at the moment you draw.

Double the Heat

Roaming Throne

With Roaming Throne on the battlefield naming 'Human' or 'Hero', Johnny Storm becomes twice as dangerous. When you draw a card while controlling another Hero, Roaming Throne causes Johnny's damage ability to trigger twice, dealing a total of 2 damage to the target opponent.

Immediate Power-up

You cast Human Torch, Johnny Storm for {2}{R}. Once he resolves and enters the battlefield, you still have priority. You choose to activate his Power-up ability. Because he entered this turn, the cost is reduced from {6}{R} to {4}. After you pay {4}, he receives three +1/+1 counters and you cannot activate Power-up again for the rest of the game.
