Sooner or later, the cards in ones HAND (not just the ones on the field) were going to be targeted sooner or later. Perhaps we'll even seen more mechanics that affect your deck (cards that haven't even been drawn!
), but that's another story altogether...
Either way, regardless of whether the card affects your hand or not, as long as it appears balanced and is a refreshing/new idea, I'm all up for it.
Considering the new changes, I'm hoping that other elements do get the ability to obtain 'better' drawing mechanics/systems, but until then, as long as Time has the best advantage of personal hand manipulation (Rewind, Hourglass, Sundial, etc.), then I'm personally satisfied.
