Suggestion for mechanics of cards casted from the graveyard.

Keyler

There are many times when you're playing with "Corrupted" gems or a similar mechanic, and a card in the graveyard "self-casts" when it reaches full mana because it has "Buried" (for example). This is sometimes very bad to the player because you might destroy your own creatures (mass removal) or cast an extra spell when the goal was to cast only four in the game (to give a couple of examples).
To improve these types of strategies, it would be interesting to add the ability to accept or reject when a card is attempted to be cast from the graveyard. Another proposal would be to add the capability to disable cards in the graveyard in the same way you can disable them in your hand, so that even if they have "Buried" and full mana, they won't be cast until you decide to re-enable them.
