Zoetic Glyph

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.

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.

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.

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

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.

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.
