Reflejo infinito

Because creatures you control enter as a copy of the enchanted creature, any "enters" triggered abilities printed on such creatures won't trigger. However, if the enchanted creature has any "enters" triggered abilities, those will trigger.

Creatures you control don't copy whether the enchanted creature is tapped or untapped, whether it has any counters on it, whether it has any Auras and Equipment attached to it, or any noncopy effects that have changed its power, toughness, types, color, or so on.

External abilities may still affect how a creature enters. For example, if your opponent controls Urabrask the Hidden, which reads, in part, "Creatures your opponents control enter tapped," a creature entering under your control will be a tapped copy of the enchanted creature.

If Infinite Reflection enters attached to a creature and then becomes attached to a different creature before its "enters" trigger resolves, each other nontoken creature you control will become a copy of the first creature.

If Infinite Reflection enters attached to a token creature, the nontoken creatures that become copies of that creature are not themselves tokens.

If Infinite Reflection leaves the battlefield or becomes attached to a different creature, none of the copy effects end. Your creatures will still be copies of whatever creature each was a copy of.

If a creature such as Clone is entering under your control, there will be two copy effects to apply: the creature's own and Infinite Reflection's. No matter what order these effects are applied, the creature will be a copy of the enchanted creature when it enters.

If you control more than one Infinite Reflection, you can apply those copy effects in any order. Creatures you control will enter as a copy of the one whose copy effect you apply last.

Infinite Reflection can enchant a creature controlled by another player.

Other "enters" replacement abilities printed on the creature entering won't be applied because the creature will already be a copy of the enchanted creature at that point (and therefore it won't have those abilities). For example, if the enchanted creature is Serra Angel, a creature that normally enters tapped will enter as an untapped copy of Serra Angel, and a creature that would normally enter with counters on it will enter as a copy of Serra Angel with no counters.

Replacement effects that modify how a permanent enters are now applied in the following order: control-changing effects (such as Gather Specimens), then copy effects (such as the abilities of Infinite Reflection and Clone), then all other effects.
