Traditional collectors use binders to store their cards
I very nearly included Gravitational Shift in today's list
In fact, it works best in the early game as most players are casting cheap Artifacts like Sol Ring and may not be able to pay the extra 1 Mana to prevent you from drawing a card
Considering the fact that nearly all moves that require coin flips need the result to be heads to execute, this means that many of the opponent's attacks can be rendered useless for a turn
(Youll see me refer to the late 90s a lot in this post, so Ill just let it be known now, that when I say the late 90s Im referring to 1998 -1999.) So, if you were actively buying card packs or begging your parents to buy them (like I was) every time they went out and you happened to obtain this card, you could be sitting on at least $10,000
In addition, we are concerned that the cost of dealing 1 damage via this effect is low and the ability to easily ignore offensive and defensive play causes more stress for players than expected, so we have decided to designate this card as a Banned Card
