Example: Varolz, the Scar-Striped has an ability that says “Each creature card in your graveyard has scavenge. The scavenge cost is equal to its mana cost.” A creature card’s scavenge cost is an amount of mana equal to its mana cost, and the activation cost of the scavenge ability is that amount of mana plus “Exile this card from your graveyard.”
Example: Volcano Hellion has the ability “This creature has echo {X}, where X is your life total.” If your life total is 10 when Volcano Hellion’s echo ability triggers but 5 when it resolves, the echo cost to pay is {5}.
Example: Fire//Ice is a split card whose halves have the mana costs {1}{R} and {1}{U}. Past in Flames reads “Each instant and sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost.” Fire//Ice has “Flashback {2}{U}{R}” while it is in your graveyard, but if you choose to cast Fire, the resulting spell has “Flashback {1}{R}.”
Example: Concerted Effort is an enchantment that reads “At the beginning of each upkeep, creatures you control gain flying until end of turn if a creature you control has flying. The same is true for fear, first strike, double strike, landwalk, protection, trample, and vigilance.” As that triggered ability resolves, each landwalk and protection ability from among creatures you control is granted to each creature you control.

Example: If a player controls a snow Forest, that player can’t block an attacking creature with snow forestwalk even if they also control a creature with snow forestwalk.
Example: A player controls Ajani’s Pridemate, which reads “Whenever you gain life, put a +1/+1 counter on this creature,” and two creatures with lifelink. The creatures with lifelink deal combat damage simultaneously. Ajani’s Pridemate’s ability triggers twice.
Example: A 2/2 creature that can block an additional creature blocks two attackers: a 1/1 with no abilities and a 3/3 with trample. The active player could assign 1 damage from the first attacker and 1 damage from the second to the blocking creature, and 2 damage to the defending player from the creature with trample.
Example: A 6/6 green creature with trample is blocked by a 2/2 creature with protection from green. The attacking creature’s controller must assign at least 2 damage to the blocker, even though that damage will be prevented by the blocker’s protection ability. The attacking creature’s controller can divide the rest of the damage as they choose between the blocking creature and the defending player.

Example: A player controls a planeswalker with three loyalty counters that is being attacked by a 1/1 with no abilities and a 7/7 with trample over planeswalkers. The active player could assign 1 damage from the first attacker and 2 damage from the second to the planeswalker and 5 damage to the defending player from the creature with trample over planeswalkers.
Example: A player attacks with a band consisting of a creature with flying and a creature with swampwalk. The defending player, who controls a Swamp, can block the flying creature if able. If they do, then the creature with swampwalk will also become blocked by the blocking creature(s).

Example: A creature has “Cumulative upkeep {W} or {U}” and two age counters on it. When its ability next triggers and resolves, the creature’s controller puts an age counter on it and then may pay {W}{W}{W}, {W}{W}{U}, {W}{U}{U}, or {U}{U}{U} to keep the creature on the battlefield.
Example: A creature has “Cumulative upkeep—Sacrifice a creature” and one age counter on it. When its ability next triggers and resolves, its controller can’t choose the same creature to sacrifice twice. Either two different creatures must be sacrificed, or the creature with cumulative upkeep must be sacrificed.
Example: A creature has two instances of “Cumulative upkeep—Pay 1 life.” The creature has no age counters, and both cumulative upkeep abilities trigger. When the first ability resolves, the controller adds a counter and then chooses to pay 1 life. When the second ability resolves, the controller adds another counter and then chooses to pay an additional 2 life.
Example: You control three creatures, one of which is phased out. You cast a spell that says “Draw a card for each creature you control.” You draw two cards.
Example: You control a phased-out creature. You cast a spell that says “Destroy all creatures.” The phased-out creature is not destroyed.

Example: The ability “Modular—Sunburst” means “This permanent enters with a +1/+1 counter on it for each color of mana spent to cast it” and “When this permanent is put into a graveyard from the battlefield, you may put a +1/+1 counter on target artifact creature for each +1/+1 counter on this permanent.”
Example: Since the card with splice remains in the player’s hand, it can later be cast normally or spliced onto another spell. It can even be discarded to pay a “discard a card” cost of the spell it’s spliced onto.
Example: Glacial Ray is a red card with splice onto Arcane that reads, “Glacial Ray deals 2 damage to any target.” Suppose Glacial Ray is spliced onto Reach Through Mists, a blue spell. The spell is still blue, and Reach Through Mists deals the damage. This means that the ability can target a creature with protection from red and deal 2 damage to that creature.
Example: Heartless Summoning says, in part, “Creature spells you cast cost {2} less to cast.” You control Heartless Summoning and cast Siege Wurm, a spell with convoke that costs {5}{G}{G}. The total cost to cast Siege Wurm is {3}{G}{G}. After activating mana abilities, you pay that total cost. You may tap up to two green creatures and up to three other creatures to pay that cost, and the remainder is paid with mana.

Example: Aether Storm is an enchantment with the ability “Creature spells can’t be cast.” This effect doesn’t stop a creature card with bestow from being cast bestowed.
Example: Garruk’s Horde says, in part, “You may cast creature spells from the top of your library.” If you control Garruk’s Horde and the top card of your library is a creature card with bestow, you can cast it as a creature spell, but you can’t cast it bestowed.

Example: Elvish Refueler has an exhaust ability that costs mana and also has an ability that reads “During your turn, as long as you haven’t activated an exhaust ability this turn, you may activate exhaust abilities as though they haven’t been activated.” Loot, the Pathfinder has an exhaust ability that is also a mana ability. If you’ve already activated both of these abilities in a previous turn, you can’t activate Loot’s mana ability during the process of activating Elvish Refueler’s exhaust ability, because you have already begun to activate a different exhaust ability.
Example: Tapestry Warden has as ability that reads “Each creature you control with toughness greater than its power stations permanents using its toughness rather than its power.”
