Miles Morales/Ultimate Spider-Man (Borderless) This version of Miles Morales is currently fetching close to $65, which is pretty spenny, but much less than it was demanding closer to release when it was sitting at $150 or more
It also led to arguments and time-wasting rulings by judges about such things as what exactly constituted a flip, how far it had to be above the table, whether it was actually touching something, and when cards could be moved around (supposedly, at least one tournament player attempted to cut his card into confetti so it would hit the whole table, although this is probably an urban legend.) As a result, they both ended up being banned in all formats, making Chaos Orb, Falling Star, and Shahrazad the only 3 cards that aren't ante cards, promo cards, or un-set cards that are banned in all formats

Hungry Flames : Instant, casting cost of two generic and one red mana
If you already have a board you can put this into play however you like and it will usually be enough to win the game with there and then
