Trample
Trample is a keyword ability that changes the rules for assigning damage in the Combat Damage Step.
From the Comprehensive Rules (November 8, 2024—Edge of Eternities)
- 702.19. Trample
- 702.19a Trample is a static ability that modifies the rules for assigning an attacking creature’s combat damage. The ability has no effect when a creature with trample is blocking or is dealing noncombat damage. (See rule 510, “Combat Damage Step.”)
- 702.19b The controller of an attacking creature with trample first assigns damage to the creature(s) blocking it. Once all those blocking creatures are assigned lethal damage, any excess damage is assigned as its controller chooses among those blocking creatures and the player, planeswalker, or battle the creature is attacking. When checking for assigned lethal damage, take into account damage already marked on the creature and damage from other creatures that’s being assigned during the same combat damage step, but not any abilities or effects that might change the amount of damage that’s actually dealt. The attacking creature’s controller need not assign lethal damage to all those blocking creatures but in that case can’t assign any damage to the player or planeswalker it’s attacking.
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.
- 702.19c Trample over planeswalkers is a variant of trample that modifies the rules for assigning combat damage to planeswalkers. The controller of a creature with trample over planeswalkers assigns that creature’s combat damage as described in rule 702.19b, with one exception. If that creature is attacking a planeswalker, after lethal damage is assigned to all blocking creatures and damage at least equal to the loyalty of the planeswalker the creature is attacking is assigned to that planeswalker, further excess damage may be assigned as the attacking creature’s controller chooses among those blocking creatures, that planeswalker, and that planeswalker’s controller. When checking for assigned damage equal to a planeswalker’s loyalty, take into account damage from other creatures that’s being assigned during the same combat damage step, but not any abilities or effects that might change the amount of damage that’s actually dealt.
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.
- 702.19d If an attacking creature with trample or trample over planeswalkers is blocked, but there are no creatures blocking it when damage is assigned, its damage is assigned to the defending player and/or planeswalker as though all blocking creatures have been assigned lethal damage.
- 702.19e If a creature with trample over planeswalkers is attacking a planeswalker and that planeswalker is removed from combat, the creature’s damage may be assigned to the defending player once all blocking creatures have been dealt lethal damage or, if there are no blocking creatures when damage is assigned, all its damage is assigned to the defending player. This is an exception to rule 506.4c, and it does not cause the creature to be attacking that player.
- 702.19f If a creature without trample over planeswalkers is attacking a planeswalker, none of its combat damage can be assigned to the defending player, even if that planeswalker has been removed from combat or the damage the attacking creature could assign is greater than the planeswalker’s loyalty.
- 702.19g Multiple instances of trample on the same creature are redundant. Multiple instances of trample over planeswalkers on the same creature are redundant.

History
Trample was introduced in Alpha.[2][3] and is generally printed on creatures with high power, such as Crash of Rhinos, or creatures with the ability to increase their power, such as Keldon Battlewagon. It has also been printed on small creatures with no intrinsic ability to gain power, such as on Defiant Elf, but these are rare.
Trample was removed from the core set with the Sixth Edition. Later on, WotC introduced a vertical cycle of creatures known as “super tramplers” in the Starter 1999 starter-level set, which were all reprinted in Seventh Edition. Lone Wolf, Pride of Lions and Thorn Elemental each can do combat damage to defending players as though they weren’t blocked. It is said that this ability was created because Wizards thought trample was too confusing, yet this new ability wasn’t taken too well in its place. Consequently, Trample was brought back in Ninth Edition.
Trample in practice
Trample in battle is really good to scratch away your opponent with the remaining damage overdone to a creature, this way you can make sure “deals damage” triggers happens and use the effect to your advantage.
