Reach is a static ability.

A creature with flying can’t be blocked except by creatures with flying and/or reach. (See rule 509, “Declare Blockers Step,” and rule 702.9, “Flying.”)

Multiple instances of reach on the same creature are redundant.

Protection is a static ability, written “Protection from [quality].” This quality is usually a color (as in “protection from black”) but can be any characteristic value or information. If the quality happens to be a card name, it is treated as such only if the protection ability specifies that the quality is a name. If the quality is a card type, subtype, or supertype, the ability applies to sources that are permanents with that card type, subtype, or supertype and to any sources not on the battlefield that are of that card type, subtype, or supertype. This is an exception to rule 109.2.

A permanent or player with protection can’t be targeted by spells with the stated quality and can’t be targeted by abilities from a source with the stated quality.

A permanent or player with protection can’t be enchanted by Auras that have the stated quality. Such Auras attached to the permanent or player with protection will be put into their owners’ graveyards as a state-based action. (See rule 704, “State-Based Actions.”)

A permanent with protection can’t be equipped by Equipment that have the stated quality or fortified by Fortifications that have the stated quality. Such Equipment or Fortifications become unattached from that permanent as a state-based action, but remain on the battlefield. (See rule 704, “State-Based Actions.”)

Any damage that would be dealt by sources that have the stated quality to a permanent or player with protection is prevented.

Attacking creatures with protection can’t be blocked by creatures that have the stated quality.

“Protection from [quality A] and from [quality B]” is shorthand for “protection from [quality A]” and “protection from [quality B]”; it behaves as two separate protection abilities.

“Protection from each [characteristic]” is shorthand for “protection from [quality A],” “protection from [quality B],” and so on for each possible quality the listed characteristic could have; it behaves as multiple separate protection abilities.

“Protection from each [set of characteristics, qualities, or players]” is shorthand for “protection from [A],” “protection from [B],” and so on for each characteristic, quality, or player in the set. It behaves as multiple separate protection abilities.

“Protection from everything” is a variant of the protection ability. A permanent or player with protection from everything has protection from each object regardless of that object’s characteristic values. Such a permanent or player can’t be targeted by spells or abilities and can’t be enchanted by Auras. Such a permanent can’t be equipped by Equipment, fortified by Fortifications, or blocked by creatures. All damage that would be dealt to such a permanent or player is prevented.

“Protection from [a player]” is a variant of the protection ability. A permanent or player with protection from a specific player has protection from each object that player controls and protection from each object that player owns not controlled by another player, regardless of that object’s characteristic values. Such a permanent or player can’t be targeted by spells or abilities the specified player controls and can’t be enchanted by Auras that player controls. Such a permanent can’t be equipped by Equipment that player controls, fortified by Fortifications that player controls, or blocked by creatures that player controls. All damage that would be dealt to such a permanent or player by sources controlled by the specified player or owned by that player but not controlled by another player is prevented.

Multiple instances of protection from the same quality on the same permanent or player are redundant.

Some Auras both give the enchanted creature protection from a quality and say “this effect doesn’t remove” either that specific Aura or all Auras. This means that the specified Auras aren’t put into their owners’ graveyards as a state-based action. If the creature has other instances of protection from the same quality, those instances affect Auras as normal.

One Aura (Benevolent Blessing) gives the enchanted creature protection from a quality and says the effect doesn’t remove certain permanents that are “already attached to” that creature. This means that, when the protection effect starts to apply, any objects with the stated quality that are already attached to that creature (including the Aura giving that creature protection) will not be put into their owners’ graveyards as a state-based action. Other permanents with the stated quality can’t become attached to the creature. If the creature has other instances of protection from the same quality, those instances affect attached permanents as normal.

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.”)

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.

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.

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.

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.

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.

Multiple instances of trample on the same creature are redundant. Multiple instances of trample over planeswalkers on the same creature are redundant.
