Horizon ExplorerHow it works & interactions with other cards

Immediate Access to Mana

The first ability of Horizon Explorer is a powerful static effect that changes how lands enter the battlefield under your control. Usually, many effects force lands to enter the battlefield tapped, but this creature overrides that restriction, allowing you to use your mana the same turn you find it.

Generating Lander Tokens

Whenever you declare an attack against a player, Horizon Explorer triggers to create a Lander token. If you are playing a multiplayer game and attack multiple players at once, this ability triggers once for each player being attacked. These tokens act as a reservoir for future land tutoring, ensuring you never miss a land drop.

The Interaction with Replacement Effects

A common mistake involves lands that have their own 'enters the battlefield tapped' abilities. If a land has a replacement effect (like 'This land enters the battlefield tapped unless...'), you choose the order in which that effect and Horizon Explorer's ability apply. However, if a spell or ability simply tells you to put a land onto the battlefield tapped without it being a replacement effect, Horizon Explorer will always result in that land entering untapped.

When to Play It

You should deploy Horizon Explorer early to maximize the value of your ramp spells. It is particularly effective in decks that use creatures to search for lands, as it turns those 'tapped' entries into 'untapped' resources, effectively refunding some of the mana spent on the spells.

Interaction examples

Ramping with the Elder

Horizon ExplorerSakura-Tribe Elder

With Horizon Explorer on the battlefield, you sacrifice Sakura-Tribe Elder to search for a basic land. Although the Elder's ability specifies the land enters the battlefield tapped, Horizon Explorer's static ability applies, and the land enters untapped instead.

Simulacrum Value

Horizon ExplorerSolemn Simulacrum

When Solemn Simulacrum enters the battlefield, its triggered ability searches for a basic land. Because you control Horizon Explorer, the land you find is placed onto the battlefield untapped, allowing you to use that mana immediately for another spell.

Utilizing the Lander Token

Horizon ExplorerLander

You attack an opponent with Horizon Explorer, creating a Lander token. Later, you pay two mana and sacrifice the Lander to search for a basic land. While the Lander token's ability says the land enters tapped, Horizon Explorer ensures it enters untapped, providing a ready-to-use mana source.
