mtg adventures in the forgotten realms collector booster box Black Theme (35 Cards) with a combination of 5 Rares and/or Mythic Rares Adventures in the Forgotten Realms

Randomly select 1 card in your opponents hand and declare 1 type (Monster, Spell or Trap), then reveal that card, and if it is the declared type, inflict 500 damage to your opponent

This is broken in token decks but good fun in loads of places

When it connects, you have to Convert it to Blitzwing, Cruel Tormentor

Numeron The engine once infamous for making Utopic Zexal works frighteningly well going second too

Or at least they would, provided there were more to work with

You can join forces with legends like Cynthia and her Garchomp ex, Ethan and Ho-Oh ex, or Arven and Mabosstiff ex or switch allegiances and battle alongside Team Rockets powerhouses, like Mewtwo ex under Giovannis command
