3. New Mechanics – Double Cards

Isle of Madness
Example of a Double Card Cloak & Dagger – that is split into two – a Cloak and a Dagger

Isle of Madness debuts a whole new mechanic that will have players seeing double. Enter the Double Card – a single card in your deck, that splits into two cards as you finish your draw. This is one of the biggest enhancements to The Elder Scrolls Legends game play since the initial release. All double Cards provide a tremendous amount of Card Advantage.

If you want to learn more about the new mechanic, check out the following article.

4. New Lane Conditions – Mania and Dementia

As players traverse the Isle of Madness, they will encounter all-new lane conditions that change up how they play their creatures. The Dementia Lane deals three damage to opponents if you control the most powerful creature, while the Mania Lane draws you a card for having the creature with the highest health.

New Game Board

Some cards within Isle of Madness can convert existing lanes into a Mania lane (e.g. Thadon, Duke of Mania) or into a Dementia lane (Syl, Duchess of Dementia), so keep a sharp mind and learn to master these new conditions so that the insanity consumes your opponents rather than you!

Note: Mania and Dementia are special lane rules that remain active even after the Duke or the Duchess leave play. Mania and Dementia are in addition to the Shadow Lane, i.e. creatures still benefit from the Cover in the Shadows. Mania and Dementia do, however, replace any other special lane rules (e.g. in Arena play mode).

8. Isle of Madness Preview during Festival of Madness

A few Isle of Madness cards or card abilities have been previewed during the 2018 Festival of Madness. Bethesda released two promotional cards, that were available for purchase for real money on only a few days during December 2018. If you did not already get these two cards, do not worry! They can be crafted with Soul Gems now. The cards intended more for fun and are not really designed to be viable cards. They do have some specific uses and Bethesda employees have said that these cards will eventually become available again in a future deal. They have not yet provided more information on when this might be the case.

The following articles provide a comprehensive review of the Preview cards Madness Beckons and Cheesemancer. You can also read more about the commercials behind The Festival of Madness.
