Assaultron Dominator 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
When this creature enters, you get(two energy counters). Whenever an artifact creature you control attacks, you may pay
. If you do, put your choice of a +1/+1, first strike, or trample counter on that creature.
Complete guide
Assaultron Dominator is a high-speed upgrade engine for your robotic army, providing the energy needed to enhance your forces on the fly. This aggressive artifact creature ensures that every charge into the red zone results in lasting improvements to your battlefield presence.
Energy and Upgrades
Assaultron Dominator provides two energy counters upon entering the battlefield. These counters are stored by you, the player, and do not disappear when phases or turns end. While this creature is on the battlefield, every attacking artifact creature you control triggers an opportunity to spend one energy counter for a permanent buff: a +1/+1, first strike, or trample counter.
Step-by-Step Resolution
When you declare one or more artifact creatures as attackers, the Dominator's ability triggers separately for each one. As each individual trigger resolves, you decide whether to pay one energy counter. If you pay, you immediately choose which of the three counter types to place on that specific attacking creature. Because this happens during the 'If you do' resolution, your opponent cannot wait to see if you pay before trying to remove the creature; they must act while the ability is still on the stack.
Common Mistakes
A common misconception is that you can pay multiple energy counters for a single attacking creature to give it multiple buffs; however, the ability only allows you to pay once per creature per attack. Additionally, remember that energy counters are not mana. Effects that produce mana of any color or type cannot generate energy, and energy cannot be used to pay for mana costs unless a card specifically states otherwise.
When to Play It
Assaultron Dominator is best utilized in aggressive decks featuring many artifact creatures. Since the energy is granted on entry, it can immediately fuel its own ability if you have other robots ready to swing. It is particularly effective when you need to push damage through blockers using trample or ensure your creatures survive combat via first strike or +1/+1 counters.
Interaction examples
If you control Ornithopter of Paradise and cast Assaultron Dominator, you get two energy counters. On your next turn, you attack with Ornithopter of Paradise. This triggers the Dominator. You pay one energy counter to place a +1/+1 counter on the Ornithopter, making it a 1/3 flying creature permanently.
If you attack with two copies of Assaultron Dominator at once, two triggers go on the stack. You can pay one energy for the first trigger to give the first Robot trample, and then pay your second energy for the second trigger to give the other Robot a +1/+1 counter.
You attack with Ornithopter of Paradise while you have zero energy counters in your Energy Reserve. The ability triggers, but as it resolves, you cannot choose to pay the energy cost. Consequently, you cannot place any counters on the Ornithopter.

- #3· Wizards of the Coast
Energy counters are a kind of counter that a player may have. They’re not associated with any specific permanents.
No other card is named in this ruling.
- #4· Wizards of the Coast
Keep track of how many energy counters each player has. Potential ways to track this include writing them down on paper or using dice, but any method that is clear and mutually agreeable is fine. (At higher levels of tournament play, dice may not be allowed for tracking counters that players have.)

- #5· Wizards of the Coast
If an effect says you get one or more
, you get that many energy counters. To pay one or more
, you lose that many energy counters. You can’t pay more energy counters than you have. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.

- #6· Wizards of the Coast
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.
