While casting spells without spending mana is great, Nashi can burn you out really fast
(1) Add to your hand, or place in your Field Zone face-up, 1 Malefic World from your Deck or GY, then Special Summon 1 Malefic monster from your Deck or Extra Deck in Defense Position, ignoring its Summoning conditions, then, if your opponent controls a monster with 2500 or more ATK, all face-up monsters they currently control lose 2500 ATK until the end of this turn
Thus, design is combined with quality and playability in any situation, catering to fans, players, and collectors alike
This card is pretty easy to set up too, since it can Special Summon itself from your hand to a column with no cards in it, albeit only once per turn this way
If you manage to drop Mystic Remora on turn one in a Commander game, then nobody is going to pay four mana and youll have too many cards in hand in seconds
