Rude Awakening: One of the best cards for strategies centered around lands, as it can be used as a finisher with many of them in play
There is something so haunting about the art for this card, seeing Kefka from under the water, like we (the viewer) are already drowning in poison and the last thing we see is Kefka laughing at us
The only difference, besides price and mana cost of the cards, is Dark Tutelage is an enchantment
(Though Ozai, the Phoenix King does this even better, allowing you to keep the excess mana.) Miirym, Sentinel Wyrm is solid, but only in green-blue-red dragon decks and nowhere else, so that's a tad limiting
The first two expansions of the game contained three lands that were well worth using twice in a turn
