Card of the Week Contest #273: Face Down, Thumbs Up

{Not an entry}Not to hate on Parasign but I'm opposed to creating a new zone named Supply Pile outside of a silver-bordered set. I feel that it would be more fun to make artifact tokens since a lot of cards care about them, but few artifacts can be printed at common outside of 'artifact sets' without disrupting the color pie.

I've been sitting on this mechanic for a while. It felt too wordy, but I wanted to keep "To cache a card" so we could force other players to take the action. I've taken liberties and created a Sacrifice CARDNAME symbol with the Beleren font Minus sign to reduce redundant CARDNAMEs. It's a little derivative to SOI's Investigate, but since we usually know what the card is, the loss of the element of surprise mitigates some of the card advantage. Note that unlike the "hostaged" cards that Curse of Arbitration or Banisher Priest exile, if you destroy the cache before its controller can retrieve the stowed card, it will never see the light of day again!

This gives players more incentive to run artifact destruction, which can often be a blank card in limited and feel particularly unrewarding when destroying tokens.

Flash supertype instead of keyword since you'll only make decisions about when to cast the spell once. Slow supertype for ETBT in the same vein since permanents only enter the battlefield once. (Yes, you can have Flash Slow cards. I've done it, it's not a good design space since you just untap them after flashing it on their end step anyway. (Maybe for Inspired permanents.))
