Ramos, Dragon Engine — ruling 1

Ramos's triggered ability counts the number of colors a spell has (from zero to five), not how many colored mana symbols are there in its mana cost or how many colors of mana you spent.

Ramos, Dragon Engine — ruling 2

If you cast a colorless spell, Ramos's triggered ability triggers, but it won't get any +1/+1 counters.

Ramos, Dragon Engine — ruling 3

Ramos's triggered ability doesn't trigger until you've finished casting a spell, including paying all of its costs. If Ramos has fewer than five +1/+1 counters on it, there's no way to add counters with a spell and pay for that spell with the newly-added counters.

Ramos, Dragon Engine — ruling 4

Ramos's triggered ability resolves before the spell that caused it to trigger. The ability will resolve even if that spell is countered or otherwise leaves the stack without resolving. In that case, use its last known information to determine what colors it was.

Ramos, Dragon Engine : règles, fonctionnement et interactions (MTG)

Ramos, Dragon Engine 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

Complete guide

Ramos, Dragon Engine is a massive artifact Dragon that thrives on diversity and color. As you cast spells, this engine builds up steam in the form of +1/+1 counters, eventually fueling an explosive burst of ten mana of all colors. It is the ultimate reward for players who love to play multi-colored decks.

Building the Engine

Ramos features a triggered ability that looks at the colors of every spell you cast. For each color a spell has, Ramos receives one +1/+1 counter. It is important to remember that this ability counts the actual colors of the spell, not the specific mana symbols in the cost or the mana spent to cast it. A spell with one black mana symbol provides one counter, while a spell with five colors provides five.

How the Trigger Resolves

The triggered ability goes on the stack after you have finished casting a spell and paid all its costs. This trigger resolves before the spell that caused it. Even if your opponent counters your spell, Ramos still gets the counters because the ability has already triggered. If the spell is removed from the stack, the game uses its last known information to determine how many colors it had.

The Mana Burst

Once Ramos has at least five +1/+1 counters, you can remove them to add two mana of every color (WUBRG) to your mana pool. This is an activated ability that can be used at any time you could cast an instant, but it is limited to once per turn. Note that you cannot use the counters gained from a spell to pay for that same spell, as the counters are only added after the spell is fully cast.

Common Pitfalls

One common mistake is assuming colorless spells provide counters; while the ability still triggers for a colorless spell, Ramos receives zero counters. Additionally, players often confuse devotion or mana cost symbols with color count. Ramos only cares about the final color identity of the spell on the stack, not how many times a specific color symbol appears.

Interaction examples

Single Color Interaction

Syr Konrad, the Grim

When you cast Syr Konrad, the Grim, Ramos, Dragon Engine detects a black spell. After you finish paying the mana cost, a trigger goes on the stack. Ramos receives one +1/+1 counter before Syr Konrad, the Grim even enters the battlefield.

Devotion vs. Color

Gray Merchant of Asphodel

Gray Merchant of Asphodel has two black mana symbols in its cost, which helps with devotion. however, it is still only one color (black). When you cast it, Ramos, Dragon Engine only receives one +1/+1 counter, not two.

Generating Massive Mana

If Ramos, Dragon Engine has five +1/+1 counters from previous spells, you can remove them to add ten mana total. This mana can be used to cast a variety of spells or high-cost finishers, but remember you can only perform this massive mana generation once during each turn.
