EnchantEnchant is a static ability, written “Enchant [object or player].” The enchant ability restricts what an Aura spell can target and what an Aura can enchant.
For more information about Auras, see rule 303, “Enchantments.”
If an Aura has multiple instances of enchant, all of them apply. The Aura’s target must follow the restrictions from all the instances of enchant. The Aura can enchant only objects or players that match all of its enchant abilities.
Auras that can enchant a player can target and be attached to players. Such Auras can’t target permanents and can’t be attached to permanents. (CR 702.5) creature
Enchanted creature has
infectInfect is a static ability.
Damage dealt to a player by a source with infect doesn’t cause that player to lose life. Rather, it causes that source’s controller to give the player that many poison counters. See rule 120.3.
Damage dealt to a creature by a source with infect isn’t marked on that creature. Rather, it causes that source’s controller to put that many -1/-1 counters on that creature. See rule 120.3.
If an object is no longer in the zone it’s expected to be in as an effect causes it to deal damage, its last known information is used to determine whether it had infect.
The infect rules function no matter what zone an object with infect deals damage from.
Multiple instances of infect on the same object are redundant. (CR 702.90).
At the beginning of your upkeep, put a -1/-1
counterTo counter a spell or ability is to cancel it: remove it from the stack without resolving it. A counter on an object or player is instead a marker that changes characteristics or interacts with rules or abilities; for example, a +1/+1 counter modifies a creature’s power and toughness.
