Misty is also vital for this deck, allowing you to stack several energies onto Dragonite or Articuno to get an early headstart
This is the the rule that really matters
your opponent can negate this effect by banishing 1 card of the same card type (Monster, Spell or Trap) as the revealed card, otherwise send the revealed card to the Graveyard
Without the ability to make use of their graveyard effect or revival mechanics, zombies are on average very weak with the only beaters being Mezuki and Zombie master, sporting 1700 and 1800 ATK respectively
Of course, since youd be playing black, cycling all these creatures into the graveyard gives you plenty of reanimation options, such as Reanimate, Victimize, and even Rise of the Dark Realms
I didn't realize it until looking properly at the card art, but there are two more Brownies lurking in the background a bit more menacingly than the main Brownie
