Dinosaur Egg {1}{G}

Notes and Rules Information for Dinosaur Egg:

• When comparing the stats of the two creature for evolve, you always compare power to power and toughness to toughness. (2023-11-10)
• Whenever a creature enters the battlefield under your control, check its power and toughness against the power and toughness of the creature with evolve. If neither stat of the new creature is greater, evolve won't trigger at all. (2023-11-10)
• If evolve triggers, the stat comparison will happen again when the ability tries to resolve. If neither stat of the new creature is greater, the ability will do nothing. If the creature that entered the battlefield leaves the battlefield before evolve tries to resolve, use its last known power and toughness to compare the stats. (2023-11-10)
• If multiple creatures enter the battlefield at the same time, evolve may trigger multiple times, although the stat comparison will take place each time one of those abilities tries to resolve. For example, if you control a 2/2 creature with evolve and two 3/3 creatures enter the battlefield, evolve will trigger twice. The first ability will resolve and put a +1/+1 counter on the creature with evolve. When the second ability tries to resolve, neither the power nor the toughness of the new creature is greater than that of the creature with evolve, so that ability does nothing. (2023-11-10)
• Multiple instances of evolve trigger separately and, similar to above, the stat comparison takes place for each one independently as they try to resolve. (2023-11-10)
• When comparing the stats as the evolve ability resolves, it's possible that the stat that's greater changes from power to toughness or vice versa. If this happens, the ability will still resolve and you'll put a +1/+1 counter on the creature with evolve. For example, if you control a 2/2 creature with evolve and a 1/3 creature enters the battlefield under your control, its toughness is greater so evolve will trigger. In response, the 1/3 creature gets +2/-2. When the evolve trigger tries to resolve, its power is greater. You'll put a +1/+1 counter on the creature with evolve. (2023-11-10)
• A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions. (2023-11-10)
• 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. (2023-11-10)

• You exile the cards face up. All players will be able to see them. (2023-11-10)
• 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. (2023-11-10)
• If the discovered card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost. (2023-11-10)
• 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. (2023-11-10)
• 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. (2023-11-10)
• 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. (2023-11-10)
• 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. (2023-11-10)
