As I mentioned a moment ago, the only downside is that we mostly played midrange and control (Dimir Control twice, plus Golgari Midrange, Jeskai Superfriends, and Esper Stax), so we didn't really get a chance to see how well the deck would perform against aggro, although Happily Ever After has a pretty insane ability to grind through disruption and eventually win the game with Happily Ever After
Jandors Ring Jandor's Ring is a 6-mana artifact that allows you to discard your most recently drawn card to draw a new one if you pay 2 mana and tap it

When Pokemon-ex is knocked out, your opponent draws 2 prize cards, adding strategic depth
