Changes to Cards in the December 27 Release

Greetings, Shadowverse Colosseumgoers! With the release of Ultimate Colosseum on December 27 (PT), we will be making changes to 1 card. Here is an explanation of what we're changing and why.

What's Changing?

1. Mjerrabaine, Omen of One's cost will be decreased by 1.

Since Mjerrabaine, Omen of One is being strengthened, it will not receive a vial bonus when being liquefied.

The Current Game Environment


After going over high-ranking match data from mid-December, we found no top deck archetypes with an overwhelming win or usage rate. We've therefore decided not to change any cards in this format. We also anticipate the Rotation environment to evolve with the release of Ultimate Colosseum on December 27 (PT). The current win rate for players going first in Rotation is 53.8% slightly up from 52.9% in early November.


Going over high-ranking match data from mid-December, we found players going first in Unlimited had a win rate of 51.9% up from 50.6% in early November. While the win and usage rates for some top deck archetypes was slightly high, we've decided that no immediate card adjustments need to be made.

Unlimited is still an ever evolving format. With the release of each card set and their additional cards we notice a change in existing deck archetypes as well as the addition of new archetypes. With the release of Ultimate Colosseum on December 27 (PT) and the following change to Mjerrabaine, Omen of One, we expect the Unlimited environment to remain fluid.

When Mjerrabaine, Omen of One was released in the Omen of the Ten card set, we saw many new decks based around Mjerrabaine appear in across multiple classes. However, these Mjerrabaine decks have not had the same level of success in Unlimited due to Mjerrabaine having a slower setup than other decks in the format. By reducing the cost of its key card, Mjerrabaine, Omen of One, we hope the archetype will see a higher usage and win rate in order to promote deck diversity in the format.


1. Mjerrabaine, Omen of One's cost will be decreased from 6 to 5.

Take Two and Open 6 Runs

These changes will also be applied to all Take Two and Open 6 decks after maintenance, even decks that are being used in the middle of a five-match run.

Future Changes to Cards

We routinely review match data in the Shadowverse Team. In order to maintain a great game environment, we change card costs and effects and boost the number of vials that are available from liquefying cards when their strength is decreased. This includes both of our constructed formats, Rotation and Unlimited. In addition to the card changes we've made in the past and card changes targeted at Rotation, we will designate cards to have a one-card restriction or card bans for Unlimited.

Any future changes to card costs and effects will be announced in advance, and then changes will generally be made the next day. The next card adjustments are scheduled for January 26 (PT).

Even if there are no changes made to cards, we'll still make an announcement. If emergency changes are deemed necessary, we may make changes, specify restrictions, or specify banned cards before the scheduled update.

That's all for this round. See you next update!
