Making the required time is super easy
It was printed in Magic 2013 (2012), but that wasnt the deck it was found in (it was in one of the Return to Ravnica Event Decks)
In a removal-heavy environment, the enchantment typing on Funeral Room gives a teeny bit more staying power than creature-based alternatives like Blood Artist and Zulaport Cutthroat
For instance, a spell with cooldown goes to the reserve exhausted, so it cant be played again until the next turn, giving it more of a lasting impact on the game than a card with fleeting (which can only ever be played once) but avoiding the swings that could happen by playing the same card twice on the same turn
Also, losing a Hand trap could be a problem, so the Deck cannot rely on them as consistently as other strategies.
Yuma's cut-in sprite is similarly based on the one from World Duel Carnival .
