DSK-337 Fractured Realm

When you unlock this door, create a token that's a copy of target creature you control, except it's a Reflection in addition to its other creature types.
//
If a triggered ability of a permanent you control triggers, that ability triggers an additional time.
//
(You may cast either half. That door unlocks on the battlefield. As a sorcery, you may pay the mana cost of a locked door to unlock it.)
