The most valuable cards so far include Avatar Aang (Borderless) at around $135, followed by Badgermole Cub, Ozai, the Phoenix King, Sozins Comet, and White Lotus Tile, all ranging between $59-$65
This decks also likely to have the most expensive new-to-Magic cards of the bunch
Since both want to attack to trigger, might I suggest Whispersilk Cloak or Rogue's Passage to swing and survive
Tarkir: Dragonstorm A booster pack of Tarkir: Dragonstorm has a few suprise stax pieces in Clarion Conqueror and Voice of Victory, good omens, epic multicolor clan cards and of course, great dragons
Simba Fighting Prince Eeyore Overstuffed Donkey Theres not a ton to say about this card because while its cool to see another Pooh character included in Disney Lorcana, this card is unlikely to see much play
