Drowner of Truth // Drowned Jungle

Drowner of Truth's triggered ability will resolve before Drowner of Truth does. If Drowner of Truth is countered or otherwise leaves the stack in response to that triggered ability, the triggered ability will still resolve as normal.

If a card loses devoid, it will still be colorless. This is because effects that change an object's color (like the one created by devoid) are considered before the object loses devoid.

Devoid works in all zones, not just on the battlefield.

Other cards and abilities can give a card with devoid a color. If that happens, it's just the new color, not that color and colorless.

A card with devoid is just colorless. It's not colorless and the colors of mana in its mana cost.

A modal double-faced card can't be transformed or be put onto the battlefield transformed. Ignore any instruction to transform a modal double-faced card or to put one onto the battlefield transformed.

The mana value of a modal double-faced card is based on the characteristics of the face that's being considered. On the stack or the battlefield, consider whichever face is up. In all other zones, consider only the front face. This is different than how the mana value of a transforming double-faced card is determined.

If an effect allows you to put a card with particular characteristics onto the battlefield without instructing you to play or cast it, you consider only the characteristics of a modal double-faced card's front face to see if that card qualifies. If it does, it enters the battlefield with its front face up. For example, if an effect allows you to put a creature card from your graveyard onto the battlefield, you can put Disciple of Freyalise onto the battlefield. However, an effect that lets you return a land card from your graveyard to your hand won't let you return Garden of Freyalise to your hand, as that card has only its front face's characteristics while in the graveyard.

If an effect allows you to play a land or cast a spell from among a group of cards, you may play or cast a modal double-faced card with any face that fits the criteria of that effect. For example, if an effect allows you to play lands from your graveyard, you can play Garden of Freyalise, but you can't cast Disciple of Freyalise.

If an effect allows you to play a specific modal double-faced card, you may cast it as a spell or play it as a land, as determined by which face you choose to play. If an effect allows you to cast (rather than "play") a specific modal double-faced card, you can't play it as a land.

To determine whether it is legal to play a modal double-faced card, consider only the characteristics of the face you're playing and ignore the other face's characteristics. For example, if an effect stops you from casting creature spells, you can't cast Disciple of Freyalise, but you can still play Garden of Freyalise.

Devoid doesn't affect the color identity of the card for the purposes of the Commander variant. For example, while Abstruse Appropriation is colorless because it has devoid, its color identity is still white and black, and it can't be included in a Commander deck where the commander's color identity doesn't include both white and black.
