Eiganjo Uprising 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

Create X 2/2 white Samurai creature tokens with vigilance. They gain menace and haste until end of turn. Each opponent creates X minus one 2/2 white Samurai creature tokens with vigilance.

Complete guide

Eiganjo Uprising is a powerful Boros sorcery that fills the battlefield with Samurai tokens for an explosive combat phase. While it gives your opponents some reinforcements, your tokens are specialized for immediate aggression and evasion. This card is perfect for breaking a board stall and ending the game through sheer numbers.

What It Does

When you cast Eiganjo Uprising, you choose a value for X. You create X tokens that are 2/2 white Samurai with vigilance. Crucially, your tokens also gain menace and haste until the end of the turn, allowing them to attack immediately and making them harder to block. However, every opponent also creates X minus one tokens of the same base type (2/2 white Samurai with vigilance), but their tokens do not gain menace or haste.

Step by Step Resolution

First, the player who cast the spell creates their X Samurai tokens. Second, those specific tokens are granted the keywords menace and haste. Third, each opponent in the game simultaneously creates their own set of X minus one Samurai tokens. If X is 1, you get one token and your opponents get zero. If X is 0, no one creates any tokens.

Common Mistakes

A common error is forgetting that only the tokens created by the caster get haste and menace. The tokens created by your opponents only have vigilance. Another mistake is miscalculating the math for X; if you spend 5 mana to cast this (where X is 3), you will get 3 tokens and your opponents will get 2 tokens each. Remember that since the tokens you create have menace, your opponents must commit at least two blockers to stop each individual Samurai you sent their way.

When to Play It

Eiganjo Uprising is a 'finisher' spell. You should aim to cast it when the value of X is high enough to overwhelm your opponent's blockers, especially since your tokens require two blockers each due to menace. It is best used during your pre-combat main phase so you can take full advantage of the haste and menace keywords provided for that turn.

Interaction examples

The Lone Samurai

Eiganjo Uprising

You cast Eiganjo Uprising where X equals 1. You create one 2/2 Samurai token with vigilance, menace, and haste. Your opponents create X minus one (1-1=0) tokens. You can attack immediately with a creature that is difficult to block, while your opponents gain nothing.

Overwhelming the Board

Eiganjo Uprising Samurai

Samurai

You cast Eiganjo Uprising for X=4. You create four 2/2 Samurai tokens. These four tokens gain haste and menace. Your opponent creates three 2/2 Samurai tokens. When you attack, your opponent only has three potential blockers, but because your tokens have menace, they would need eight blockers to stop all four of your attackers. At least one or more of your Samurai will likely deal damage directly.
