Alongside the new EDH card City of Fire, Mana Crypt also sneakily deals nine damage to you instead of three, which can unexpectedly put you in a bad position
He can protect himself via Ward by sacrificing a legendary creature or artifact
Turbo Special makes that gap a lot less painful, and also makes folks a lot more comfortable sending in cards knowing theyll get them back in time for key events and, in the case of ultra-modern stuff, back before the market on that card has a chance to completely change
Useful as a way to produce more coloured mana as well in combination with artifact lands or Talisman
To be clear, that's not a fudge
Players should be free to open packs, craft cards, and purchase card styles without worrying about doing things "the right way." I get itif there's one thing Magic players love, it's learning to optimize their gameplay, but there shouldn't be an "optimal way" to bling out your deck
