yugioh chazz manga deck profile Generic Anime Trading Card Deck:

It can essentially nullify a trap beastie, but only when it is flipped, and even then they can still defend with it and have it die and they are able to get another one of that beastie or a separate beastie with the same cost in their deck

While Into the Pit is half the cost of Citadel, I just dont see it knocking Citadel out of many decks, aside from token decks

The card's effect is fairly simple, allowing you to draw 2 card for no cost

It can't be the target of the triggered ability of Mystic Sanctuary

However, he also has three exhaust tap abilities, with one green giving three mana of any colour, one blue drawing three cards, and one red dealing three damage to any target
