Carte Magic Prossh, Skyraider of Kher

Prossh, Skyraider of Kher 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.

01

Official card text

When you cast this spell, create X 0/1 red Kobold creature tokens named Kobolds of Kher Keep, where X is the amount of mana spent to cast it. Flying Sacrifice another creature: Prossh gets +1/+0 until end of turn.

Complete guide

Prossh, Skyraider of Kher is a powerhouse commander that brings its own small army to the battlefield. This legendary Dragon rewards you for casting it by flooding the board with Kobolds, which it can then consume to increase its power. Whether you are aiming for commander damage or sacrifice synergies, Prossh is a engine of destruction.

A Casting Trigger, Not an Entry Trigger

The most important thing to remember about Prossh is that its token-generating ability triggers when you cast the spell, not when it enters the battlefield. This means the ability goes on the stack on top of Prossh itself. The tokens will be created and enter the battlefield before Prossh even finishes resolving. Furthermore, if you put Prossh onto the battlefield from your graveyard or library without casting it, you won't get any tokens at all.

Calculating Your Kobolds

The number of tokens created depends on the total amount of mana spent to cast Prossh. This includes its base cost of six mana, but also includes the 'commander tax' if you are casting it from the command zone for the second or third time. If an effect makes the spell cost more to cast, you get more tokens; if an effect allows you to cast it for free, you will get zero tokens.

Sacrifice for Power

Prossh features an activated ability that allows you to sacrifice another creature to give Prossh +1/+0 until end of turn. This ability has no activation cost other than the sacrifice, meaning you can use it as many times as you have creatures to feed it. This is a great way to trigger 'death' abilities while simultaneously threatening lethal flying damage.

When to Deploy the Skyraider

Prossh is best played when you have a board state that benefits from creatures dying or entering the battlefield. Because it creates multiple bodies for a single card, it is an excellent follow-up to a board wipe. Always keep an eye on your total mana spent, as a late-game Prossh can easily generate ten or more Kobolds of Kher Keep at once.

Interaction examples

Death by a Thousand Cuts

With Syr Konrad, the Grim on the battlefield, you cast Prossh for six mana, creating six Kobolds of Kher Keep. Once Prossh resolves, you use its ability to sacrifice each Kobold. Since Syr Konrad triggers whenever another creature dies, he will deal 1 damage to each opponent for every Kobold sacrificed, while Prossh grows to an 11/5 flyer.

Devotion and the Dragon

If you have Prossh on the battlefield and cast Gray Merchant of Asphodel, Prossh contributes one black pip to your devotion. However, notice that the Kobolds of Kher Keep are red and have no mana cost, so they do not contribute to your devotion to black. If you need to clear board space, you can sacrifice the Merchant to Prossh after its entry trigger resolves to set up for a graveyard recursion play.

How it works : Prossh, Skyraider of Kher

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    The amount of mana you spent to cast this creature is usually equal to its mana value. However, you also include any additional costs you pay, including the commander tax.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    You can't choose to pay extra mana to cast a creature spell unless something instructs you to.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    The first ability triggers when you cast Prossh, not when it enters the battlefield. This means that it will resolve before Prossh, so any Kobold tokens it creates will be put onto the battlefield before Prossh. If Prossh enters the battlefield without being cast, the ability will not trigger.

    No other card is named in this ruling.
