A Nexus of Fate deck was my first thought as far as combo shells go since those decks were already playing Drawn from Dreams back in the previous Standard format
Honorable Mentions Before I mention the un-set cards, Jumbo Cactuar has the humble printed power of 1, but it's attack trigger sends it soaring over the other cards on this list as it reaches 10,000
Additional copies of a card, as you might expect, can be obtained from opening Pokmon TCG Pocket booster packs, and you need to have more than two copies of a card to get a flair you also cant spend cards on a flair if it would take you below two of that card
You can also sacrifice for mana to Ashnod's Altar, for damage to Goblin Bombardment and then make a mana on arrival with Mana Echoes or Carnival of Souls
The first is strong as you are tossing on two abilities and likely a counter onto a dork, and the next is a drain ability if you have a Vampire you want to give up for the cause of killing a dork or finish off a planeswalker you just attacked into
