Saprazzan BreakerHow it works & interactions with other cards

Unblockable Mechanics

The activated ability of Saprazzan Breaker costs one blue mana and requires you to mill the top card of your library. If the card put into your graveyard is a land card, the Breaker gains a status effect that prevents it from being blocked for the remainder of the turn. If the card milled is not a land, the ability still resolves fully, but the creature remains blockable.

Step-by-Step Resolution

First, you pay the cost of one blue mana to put the ability on the stack. Upon resolution, you move the top card of your library to your graveyard. The game then checks the type of that specific card; if it carries the 'Land' type, a continuous effect is created. This effect lasts until the end of the turn, even if the land card is later moved from the graveyard to another zone.

Strategic Timing and Mistakes

A common mistake is waiting until after blockers are declared to activate the ability. To ensure Saprazzan Breaker cannot be blocked, the ability must resolve and the land must be milled during the Declare Attackers step at the latest. If a creature has already been legally declared as a blocker for Saprazzan Breaker, making it unblockable afterwards will not remove the blocker or cause the damage to go through to the player.

When to Activate

You should use this ability when you have spare mana and need to push through the final points of damage. Since you can activate the ability multiple times in response to itself or after seeing the result of a previous activation, you can keep milling until you hit a land, provided you have the mana to spend.

Interaction examples

Digging for the Win

With Saprazzan Breaker on the battlefield, you move to your combat phase and declare it as an attacker. Before your opponent can block, you pay one blue mana. You mill a card and it is an Island. Because a land was milled, Saprazzan Breaker can no longer be blocked this turn, ensuring it deals 3 damage to your opponent.

Managing Your Library

Solemn Simulacrum

If you need a land to guarantee unblockability but have few left in your deck, playing Solemn Simulacrum first to search for a basic land will thin your deck. This actually decreases the mathematical probability that Saprazzan Breaker's ability will hit a land card on the next mill, so plan your sequencing carefully based on whether you need the land on the field or in the graveyard.

Interaction with Type Doublets

Roaming Throne

If you have Roaming Throne on the battlefield naming 'Beast', it is important to note that Saprazzan Breaker's ability is an activated ability, not a triggered one. Roaming Throne will not cause you to mill twice or check for a land twice when you pay the blue mana; you only get the effect once per activation.
