Since its release, this card has been reprinted a few times (most recently as part of Wilds of Eldraines Enchanting Tales bonus sheet) and always as a rare or mythic rare - as WotC attempts to right the wrong of making it a common all those years ago
Most notably 5th edition was the last Core Set to feature game concepts like 'fast effects' and 'interrupts', being replaced by the "stack" in 6th Edition, and all spells being either Instants or Sorceries.
[4] Its not that low mana curve decks dont need 3-4 lands in play, its just that you can often get away with missing land drops
I know its not the complete package, but if youre looking for more ways to tutor up equipment, Cloud, Midgar Mercenary can help you big time
The extra knowledge you get can affect a lot of decisions such as scry and surveil, and youll hardly ever miss a land drop with this card around
You can test a deck before spending serious money, build a casual Commander list without selling a vital organ to the Reserved List, or create a cube where everyone gets to play powerful cards instead of watching one person shuffle a mortgage payment
