Zoetic Glyph

Official Ruling

A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions.

Official Ruling

If the discovered card has in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

Official Ruling

Effects that modify a creature's power and/or toughness, such as the ones created by Giant Growth, will apply to the creature no matter when they started to take effect. The same is true for any counters that change its power and/or toughness and effects that switch power and toughness.

Official Ruling

Some spells and abilities that cause you to discover may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve and you won't discover.

Official Ruling

If you cast a spell "without paying its mana cost", you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the spell has any mandatory additional costs, you must pay those to cast it.

Official Ruling

If you can't cast the discovered card (perhaps because there are no legal targets for the spell), you'll put it into your hand.

Official Ruling

If the artifact was already a creature, its base power and toughness will become 5/4. This overwrites any previous effects that set the creature's base power and toughness to specific values. Any power- or toughness-setting effects that start to apply after Zoetic Glyph becomes attached to the artifact will overwrite this effect.

Official Ruling

If the creature Zoetic Glyph would enchant is an illegal target as Zoetic Glyph tries to resolve, it won't resolve. It's put into your graveyard from the stack, not the battlefield, so its last ability won't trigger.

Official Ruling

If you discover an adventurer card, split card, or modal double-faced card, you might be able to cast that card with either set of characteristics depending on the effect's discover value. For example, if you discover 4 and reveal Galvanic Giant (an adventurer card from Wilds of Eldraine with a mana value of 4), you could cast Galvanic Giant, but not Storm Reading (its Adventure, which has a mana value of 7). If you discover 7 and reveal Galvanic Giant, you could cast either Galvanic Giant or Storm Reading.

Official Ruling

The mana value of a split card is determined by the combined mana cost of its two halves. If discover allows you to cast a split card, you may cast either half (as long as its mana value is less than or equal to the effect's discover value) but not both halves.

Official Ruling

You exile the cards face up. All players will be able to see them.

Official Ruling

When you discover, you must exile cards. The only optional part of the ability is whether you cast the exiled card or put it into your hand.

Official Ruling

The resulting artifact creature will be able to attack on your turn if it's been under your control continuously since the turn began. That is, it doesn't matter how long it's been a creature, just how long it's been on the battlefield.

Official Ruling

The artifact retains any types, subtypes, or supertypes it has. Notably, an Equipment that becomes an artifact creature usually can't be attached to another creature. If it was attached to a creature, it becomes unattached.
