Carte Magic Waterbending Lesson

Waterbending Lesson is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

01

Official card text

Draw three cards. Then discard a card unless you waterbend {2}. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for {1}.)

Complete guide

Dive into the flow of resources with Waterbending Lesson, a versatile Sorcery from the Lesson subtype. This card provides significant card advantage while allowing you to use your board presence to preserve your hand size. Master the art of using your tools to fuel your mind without spending a single extra mana.

What it Does

Waterbending Lesson costs three generic and one blue mana to cast. Upon resolution, you draw three cards, then you must choose: either discard a card from your hand or pay the waterbend cost of two generic mana. Waterbend allows you to tap any untapped artifacts or creatures you control to pay for its generic mana requirement instead of spending actual mana.

How it Resolves Step by Step

First, the spell is cast and put onto the stack. Once it resolves, you immediately draw three cards. Next, the game checks if you want to waterbend. You may choose to tap up to two untapped artifacts or creatures you control, or spend two generic mana, or a combination of both. If you successfully pay this cost of two, you keep all your cards. If you choose not to or cannot pay, you must discard one card from your hand.

Common Mistakes

A common error is trying to tap a creature for mana using its own ability and then also using it for waterbend; you cannot tap a single permanent twice for the same cost. Additionally, remember that waterbend is paid during the resolution of the spell, not while casting it. Unlike Convoke, waterbend on this card is an optional cost to prevent a discard effect, not a way to reduce the initial four-mana casting cost.

When to Play it

This card is best played when you have a board of utility artifacts or creatures that aren't currently attacking or blocking. Since you draw the cards before the discard check, it is an excellent way to dig for answers. If you have at least two permanents to tap, it effectively becomes a 'Draw 3' for four mana with no downside.

Interaction examples

Artifact Synergy

You cast Fabricate to find a key artifact and put it into your hand. Later, you cast Waterbending Lesson. After drawing three cards, you tap the artifact you just played and a creature to satisfy the waterbend {2} cost. This ensures you keep the artifact you searched for earlier plus all your new cards.

Filling the Graveyard

If your goal is to put specific cards into your graveyard for a later play, you might cast Waterbending Lesson and deliberately choose not to waterbend, even if you have creatures to tap. After discarding a high-value target, you could follow up with Windfall to cycle through your deck, knowing you've already sculpted your graveyard.

How it works : Waterbending Lesson

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    If an artifact or creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell or activating an ability with waterbend will result in the artifact or creature being tapped before you pay the spell's costs. You won't be able to tap it again for waterbend. Similarly, if you sacrifice an artifact or creature to activate a mana ability to pay a cost with waterbend, that artifact or creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for waterbend.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    You can tap any untapped creature or artifact you control to pay a waterbend cost, even one you haven't controlled continuously since the beginning of your most recent turn.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Even if the cost of the spell or ability that waterbend is part of increases or decreases, you still may only tap artifacts or creatures to pay for costs up to the amount of the generic mana in the waterbend cost.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    "Waterbend [cost]" means "Pay [cost]. For each generic mana in that cost, you may tap an untapped artifact or creature you control rather than pay that mana."

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    If a waterbend cost is part of the total cost to cast a spell or activate an ability, you may tap an untapped artifact or creature you control rather than pay one generic mana in that total cost any number of times up to a maximum of the amount of generic mana in the waterbend component of that total cost.

    No other card is named in this ruling.
