Rotation | Rotation

[OldTrees]

According to the new Notes, creatures are not considered "ready" unless they glow.
Yes, you can "save" Mind Flayer from being delayed by taking away its readiness before playing Rotation.

"Ready" means unaffected by summoning or activation sickness. It is displayed by the glow on creatures who can activate their abilities.

This does not communicate that the glow is required for it to be considered "Ready"

So Rotation is:
Use all the activated abilities of your Readied creatures
[optional] Play Mitosis/Butterfly Effect or use Mutation on your opponent's creatures
Play Rotation
Use all the activated abilities of your creatures
The creatures with activated abilities your opponent controls are delayed for 2 turns

No, you need to play 2 Rotations in one turn to delay your opponent's creatures.
As implied by the notes, the creatures without activated abilities that your opponent controls will also be delayed.

No, you need to play 2 Rotations in one turn to delay your opponent's creatures.
As implied by the notes, the creatures without activated abilities that your opponent controls will also be delayed.

So you no longer are basing Rotation off summoning sickness? Please clarify that everywhere.

Creatures without activated abilities do not have summoning sickness if they were played last turn. This demonstrable by playing Mitosis.
Creatures that did not have summoning sickness on their turn do not have summoning sickness on your turn. Their summoning sickness was already removed.

If you do not mean Ready as related to summoning sickness like Shard of Readiness is related to, then please clarify that.

A creature is "ready" iff they are glowing.
If a creature is not glowing, they are not "ready" and are affected by the first mechanic of Rotation as expanded in the Notes.
If a creature is not affected by summoning sickness but has no ability as of yet, it is not glowing, and therefore is not "ready", because its "readiness" is not displayed, as explained in the Notes.

The first sentence in the notes does not match yet.

"Ready" means unaffected by summoning or activation sickness.

In the first sentence the definition of Ready is defined as being unaffected by summoning sickness.
Is unaffected by summoning sickness <-> Is ready
This does not match what you mean by ready
Please change this sentence to match your intent.

What you define as ready by "glowing" is what I asume is the ability to click on a creature who may use its active effect, however this creates more issues than it solves. In this case using a creatures ability and then playing this card would define the creature as "not ready" and I may be mistaken, but you never see a "glow" around the opponent's creatures.

Using a creature's ability and then using this card would cause the creature to glow and "define" the creature as ready.
True, there is no way to see glowing creatures on the opponent's side of the field in the current version of the game. That does not mean it's impossible to make a card that causes the creatures on the opponent's side of the field to glow.
