DH: Building these decks called for us to decide color identity for the chosen game itself, but also the gameplay we desired from them
To play a full game, you need two sets, totaling around $32
Along similar lines, the card is definitely worse in sideboarded games where most decks are more likely to draw that key piece of interaction, and the more copies of Unsubstantiate you play, the harder it is to sideboard them out when you decide theyre bad against your opponents post-sideboard configuration
It could also mean a new type of card or item that can be equipped to a character like Armor or a weapon
For one, because most people will expect to be able to actually use the card they shelled money for, even if they dont plan on it
Its worth only whatever the buyer paid for it, probably less than a dollar
