Sméagol, Helpful Guide

Sméagol, Helpful Guide doesn't need to have been on the battlefield when the creature died. For example, if a creature dies under your control during combat on your turn and you cast Sméagol, Helpful Guide during your second main phase, its first ability will trigger at the beginning of your end step.

Sméagol, Helpful Guide's first ability will trigger only once during your end step, no matter how many creatures died under your control this turn. However, if no creatures have died under your control so far this turn as your end step begins, the ability won't trigger at all. It's not possible to cause a creature to die under your control during the end step in time to have the ability trigger.

As the Ring tempts you, you get an emblem named The Ring if you don't have one. Then your emblem gains its next ability and you choose a creature you control to become (or remain) your Ring-bearer.

The Ring can tempt you even if you don't control a creature. In this case, abilities that trigger "whenever the Ring tempts you" will still trigger.

If the creature you choose as your Ring-bearer was already your Ring-bearer, that still counts as choosing that creature as your Ring-bearer for the purpose of abilities that trigger "whenever you choose a creature as your Ring-bearer" or abilities that care about which creature was chosen as your Ring-bearer.

The Ring gains its abilities in order from top to bottom. Once it gains an ability, it has that ability for the rest of the game.

Each time the Ring tempts you, you must choose a creature if you control one.

Each player can have only one emblem named The Ring and only one Ring-bearer at a time.

Some spells and abilities that cause the Ring to tempt you may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. The Ring won't tempt you.
