Lathnu Hellion 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.

.
Complete guide
Lathnu Hellion is a high-speed, high-impact creature that rewards players for managing their energy resources. This volatile Hellion can end games quickly, provided you have the energy counters to keep it on the battlefield. Understanding how to generate and spend energy is key to harnessing its full potential.
What It Does
Lathnu Hellion is a 4/4 creature with Haste for only three mana, making it an aggressive threat. When it enters the battlefield, you receive two energy counters ({E}{E}). However, this power comes at a cost: at the beginning of your end step, you must pay two energy counters or sacrifice the Hellion.
Step-by-Step Resolution
First, when Lathnu Hellion enters the battlefield, its triggered ability goes on the stack. When it resolves, you gain two energy counters, which are placed on you, the player. Second, during your end step, a second triggered ability occurs. As this resolves, you choose whether to pay two energy counters from your current total. If you cannot or choose not to pay, you must sacrifice the Hellion. Note that energy counters do not expire at the end of turns or phases.
Common Mistakes
A frequent error is treating energy counters like mana; they are actually a type of counter held by the player and do not disappear until spent. Another mistake is forgetting that you can use energy counters gained from other cards to pay for the Hellion's upkeep. Additionally, if the Hellion leaves the battlefield before the end step, you still keep the two energy counters it provided upon entry.
When to Play It
Play Lathnu Hellion when you need immediate pressure. Because it has Haste, it can attack the same turn it is cast. It is most effective in decks that can generate additional energy to sustain it for multiple turns, or in aggressive builds where a single 4/4 swing is enough to secure a victory.
Interaction examples
If you control Roaming Throne with 'Hellion' chosen as the creature type, Lathnu Hellion's entry trigger will trigger twice. You will gain four energy counters instead of two, allowing you to keep the Hellion around for two end steps without needing other energy sources.
If you cast Lathnu Hellion while you have zero energy, it enters and gives you two energy counters. You attack for 4 damage. At your end step, you can pay those two energy counters to keep it. If you then trade your Solemn Simulacrum in combat later, it doesn't help the Hellion, but you've already used the Hellion's own energy to survive the first night.
When Lathnu Hellion enters, you receive two energy counters. You can use an Energy Reserve card as a physical reminder on the table to track these counters using dice or beads. During your end step, you remove two counters from the reserve to satisfy the Hellion's maintenance cost.

Keep track of how many energy counters each player has. Potential ways to track this include writing theme down on paper or using dice, but any method that is clear and mutually agreeable is fine.

Energy counters aren't mana. They don't go away as steps, phases, and turns end, and effects that add mana "of any type" can't give you energy counters.
