Eager BeaverHow it works & interactions with other cards

What It Does

Eager Beaver features a triggered ability that activates specifically when it enters the battlefield. This ability allows you to target any permanent on the battlefield—including lands, creatures, artifacts, or even Eager Beaver itself—and untap it. As a Host creature, it functions as a standard creature but is designed to interact with 'Augment' cards to modify its abilities.

How It Resolves Step by Step

First, Eager Beaver must successfully enter the battlefield from the stack or any other zone. Once it is on the battlefield, its triggered ability is placed on the stack, and you choose a target permanent. When the ability resolves, you decide whether or not to untap that permanent. Because the ability says 'you may,' you are not forced to untap the target if the situation has changed.

Common Mistakes

A common error is forgetting that this ability can target permanents you don't control. While usually beneficial to untap your own cards, you can untap an opponent's permanent if required by the board state. Additionally, remember that as a triggered ability, it can be responded to by opponents before the untap occurs.

When to Play It

This card is best played when you have a high-value permanent that is already tapped, such as a land that produces multiple mana or a creature with a powerful activated ability. It effectively reduces its own mana cost by untapping a land, or it can provide 'pseudo-vigilance' by untapping a creature that just attacked.

Interaction examples

Ramping with Lands

You tap three lands to cast Eager Beaver. Upon its entry, its ability triggers, targeting one of the tapped lands. You untap that land, effectively making Eager Beaver cost only two mana for that turn.

Optimizing Land Search

Solemn Simulacrum

You cast Solemn Simulacrum and search for a basic land, which enters the battlefield tapped. Next, you cast Eager Beaver. Its triggered ability targets the tapped basic land you just searched for. You untap it, allowing you to use that extra mana immediately instead of waiting for the next turn.

Blocking Readiness

Sakura-Tribe Elder

If you attack with Sakura-Tribe Elder during your turn, it becomes tapped. By casting Eager Beaver in your second main phase, you can untap Sakura-Tribe Elder. This leaves the Elder ready to block during your opponent's turn before you decide to sacrifice it for a land.
