1) Fiend Comedian
Similar to Lullaby of Obedience, and any other card that offer both effects, you should use this card in decks that would benefit you no matter which of the both ways things go.
Fiend Comedian is capable of BANISHING the ENTIRE of your opponent's graveyard, which could be deadly. Of course, you will end up milling quite plenty too, should you call it wrongly.
Of course, you can always minimise the cost by calling the toss early in the game, but where is the fun in that? Late game stage, it will also be more costly for your opponent.
PK FIRE or Lightlords mirror match maybe? Just don't use it in a deck that utilises Pot of Desires. You will probably deck out very fast. Infernoids can also give it a try.
Last but not least, remember to pray that you are like Joey Wheeler, whose luck never seems to run out.
2) Burn Out
Similar to Fiend Comedian, Burn Out banishes cards in the graveyard. However, you would be banishing your own cards as well. An assured banish of your opponent's grave, at the cost of your own. It also has its own activation requirement, although it may be pretty easy to fulfill in the current meta.
The fact that it only banishes monsters might also mean that it can be abused in trap monsters deck like Burgesstoma.
3) Xing Zhen Hu
4) Aurora Paragon
Paragon is an interesting card, and I came across it while searching for Normal Rare cards after looking through Xing Zhen Hu Replica. I find it interesting and hilarious that it gets destroyed upon a monster's normal summon. But it is a cool tech to have in decks that rarely performs a normal summon. Like the trap-based deck Burgesstoma? Damn it seems like that archetype keeps popping out at every example. Infernoid is also another deck that performs little to no normal summons. I would recall DAM SON drawing and passing every single turn when I summoned Jowgen against his Infernoid deck.
And from this card's tip page on Yugioh Wikia, By Order of the Emperor works well with this card's effect. It nets you a draw and prevent this card's destruction.
5) Localised Tornado
A single card capable of returning your entire grave to the deck, along with your hand as well though. I am bewildered by this card's effect, but don't even know where to start? How to abuse it? When can it be useful? Any theoretical good use to this card's effect?
I shall just leave it here and hopefully someone may find good use to it.
It can prevent a deck out, lol.
CardWatch's list seems to be getting shorter and shorter. But it was never my intention to keep it restricted to a certain number. I just constantly add cards to the article during the month, and keep extending the article until it is time to be published. As I invest more time into composing other articles, my database-scouting time decreases, and hence the shorter CardWatch articles as each month passes.
