The Standard meta is going to get shook up something fierce with the release of Origins, so anything could happen, but if Nissa pops up at top tables in some early Standard tournaments, I can easily see her pushing the upper limits of standard playable mythics
With Ursulas Necklace in play, if you play A Whole New World, does the trigger happen after it before AWNW resolves When you play A Whole New World, Ursulas Shell Necklace triggers after, so you can draw additional cards after resolving A Whole New World
Thats the idea with Volatile Stormdrake too
Anyone who hoards cards will be punished as well
Them: Haven't won a match in weeks
Including cards from the D&D sets that allow you to roll a D20 increase your chances of activating all its triggered abilities and fits the theme of a more chaotic deck
