It plays into the flavor of having two forms by mechanically affecting the game based on whether it's tapped or untapped
Its effectiveness in life gain decks (the fifth most popular theme on EDHREC), and its ability to completely end a game in something like a token or Soldiers deck, are why I ranked The Wind CrystalThe Wind Crystal so high
Two mana and below covers pretty much all the best utility artifacts in the game, so there are few problems you cant solve with this card and a well-built deck
And as a FINAL FANTASY VIII enjoyer (yeah, that's right!), you only play as Laguna in flashback sequences in the game, and I knew I'd want to get one of those into the set
For example, if an attacking creature would deal 8 damage to you and you control two Ancient Adamantoises, you'll choose which of those Ancient Adamantoises will take that damage
Some of the reprints are really good
