Basilica GuardsHow it works & interactions with other cards

Understanding Extort

The primary function of Basilica Guards is its Extort ability. Whenever you cast any spell—be it a creature, instant, sorcery, or artifact—this ability triggers and goes on the stack on top of that spell. As the ability resolves, you are given a choice: you may pay one mana that is either White or Black. If you pay, every opponent loses 1 life, and you gain life equal to the total life lost this way. Note that because it has Defender, Basilica Guards cannot attack unless an effect specifically allows it to do so.

The Resolution Process

Extort triggers the moment you finish casting a spell. The trigger resolves before the original spell does. This means you can gain life and drain your opponent even if the spell you cast is eventually countered. You only decide whether to pay the {W/B} cost when the Extort ability actually resolves, not when you cast the spell. You can only pay this cost once per trigger, per permanent with Extort you control.

Common Pitfalls

A common mistake is thinking you can pump multiple mana into a single Extort trigger to drain for more; however, the rules state you may only pay the cost a maximum of one time for each trigger. Additionally, the life gain is dependent on life being lost. If an opponent has an effect that prevents their life total from changing, you will not gain life from them. Finally, remember that Extort does not target, so it can bypass keyword abilities like Hexproof or Shroud.

When to Play Basilica Guards

Basilica Guards is most effective in 'stally' decks that plan for a long game. Its 4 toughness allows it to block many early-game threats effectively. It shines when you have extra mana available each turn, allowing you to weaponize your utility spells and late-game draws into direct damage that bypasses the combat phase entirely.

Interaction examples

Triggering the Drain

Solemn Simulacrum

With Basilica Guards on the battlefield, you cast Solemn Simulacrum. The Extort ability triggers and is put on the stack. You choose to pay {W}. Your opponent loses 1 life and you gain 1 life. Afterward, Solemn Simulacrum resolves and enters the battlefield, allowing you to search for a land. Even if your opponent used a spell to counter the Golem, the life drain from Extort would still have happened.

Doubling the Tax

Roaming Throne

You control Basilica Guards and Roaming Throne, for which you chose 'Human' as the creature type. When you cast any spell, the Extort ability of Basilica Guards triggers. Because of Roaming Throne, it triggers an additional time. You now have two separate Extort triggers on the stack. You may pay {W/B} for the first one, then pay {W/B} for the second one, resulting in a total of 2 life lost by each opponent and 2 life gained by you.
