Trample
From MTG Salvation Wiki
Trample is a keyword ability that changes the rules for assigning damage in the Combat Damage Step. An attacker with trample can potentially deal damage to the defending player even if it is blocked. Trample 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 is primarily placed in green on the Color Wheel, although other colors have received the ability.
Trample was removed from the core set after 6th Edition. It was brought back in 9th Edition. Wizards introduced a vertical cycle of ctreatures known as "super tramplers" in the Starter 1999 starter-level set, they were all reprinted again in 7th 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.
In a "Ask Wizards" column, Aaron Forsythe said about Trample:
| “ | Three things combined to get trample back in the Core Set with Ninth Edition. One, newer players were running into trample in expert-level sets and not knowing how it worked. Most keywords without reminder text in black-bordered sets--flying, swampwalk, first strike, etc.--are clearly explained in the Core Set. But trample (and protection) were not, meaning the first time players saw it, they were clueless. Two, our replacement for trample (the Thorn Elemental ability) was not particularly easy to understand either. Three, our rules people came up with good reminder text for the mechanic, allowing it to exist happily in the Core Set.
We're not trying to dumb the game down. In fact, we want the Core Set to be a teaching tool, which means we want it to cover as much ground as realistically possible, which is why we worked so hard for a way to get trample (and protection and equipment) into Ninth Edition. [1] | ” |

[edit] Reminder text
The latest reminder text for Trample reads "If this creature would deal enough combat damage to its blockers to destroy them, you may have it deal the rest of its damage to defending player."
