Guardian of the HallsHow it works & interactions with other cards

A Growing Threat

Guardian of the Halls features two distinct traits: the Trample keyword and a powerful activated ability. Trample allows it to deal excess combat damage to the defending player or planeswalker after dealing lethal damage to blockers. Its activated ability costs seven mana, including two green, to place three +1/+1 counters on itself permanently.

Activating the Ability

To grow your Guardian, you must pay five generic and two green mana. This is an activated ability that can be used at any time you have priority, including during your opponent's turn or in response to a removal spell. Once the ability resolves, the Guardian receives three +1/+1 counters, increasing its power and toughness simultaneously.

Timing and Strategy

Because the ability does not require the Guardian to tap, you can activate it even if the creature is already attacking or blocking. A common mistake is forgetting that you can activate this multiple times in a single turn if you have the mana. This makes the Guardian a dangerous mana sink during long games where you have accumulated many lands or mana producers.

Interaction examples

Fast Growth with Llanowar Elves

Llanowar Elves

You play Llanowar Elves on turn one. On turn two, you use the mana from Llanowar Elves and two lands to cast Guardian of the Halls. Later in the game, the extra green mana provided by Llanowar Elves helps you reach the seven mana required to activate the Guardian's counter-placing ability faster.

Color Fixing for Evolution

Birds of Paradise

If you are playing multiple colors, you might lack the two specific green mana symbols needed for the Guardian's ability. By tapping Birds of Paradise for green mana, you satisfy the strict color requirements of the {5}{G}{G} cost, allowing you to buff the Guardian even if your lands only produce other colors.

Trample Overload

Imagine Guardian of the Halls is blocked by a 1/1 creature. Before damage is dealt, you spend seven mana to put three +1/+1 counters on it, making it a 5/6 creature. Because of Trample, it deals 1 damage to the blocker and 4 damage directly to the opponent.
