DeathtouchDeathtouch is a static ability.
A creature with toughness greater than 0 that’s been dealt damage by a source with deathtouch since the last time state-based actions were checked is destroyed as a state-based action. See rule 704.
Any nonzero amount of combat damage assigned to a creature by a source with deathtouch is considered to be lethal damage for the purposes of determining if excess damage is being dealt.
The deathtouch rules function no matter what zone an object with deathtouch deals damage from.
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 deathtouch.
Multiple instances of deathtouch on the same object are redundant. (CR 702.2) (Any amount of damage this deals to a creature is enough to
destroyThe only ways a permanent can be destroyed are as a result of an effect that uses the word “destroy” or as a result of the state-based actions that check for lethal damage (see rule 704.5g) or damage from a source with deathtouch (see rule 704.5h). If a permanent is put into its owner’s graveyard for any other reason, it hasn’t been “destroyed.”
A regeneration effect replaces a destruction event. See rule 701.19, “Regenerate.” (CR 701.8) it.)
RenownRenown is a triggered ability. “Renown N” means “When this creature deals combat damage to a player, if it isn’t renowned, put N +1/+1 counters on it and it becomes renowned.”
Renowned is a designation that has no rules meaning other than to act as a marker that the renown ability and other spells and abilities can identify. Only permanents can be or become renowned. Once a permanent becomes renowned, it stays renowned until it leaves the battlefield. Renowned is neither an ability nor part of the permanent’s copiable values.
If a creature has multiple instances of renown, each triggers separately. The first such ability to resolve will cause the creature to become renowned, and subsequent abilities will have no effect. (See rule 603.4) (CR 702.112) 1 (When this creature deals combat damage to a player, if it isn't

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.
