Theres also the distinction between instants and sorceries that could come into play for your D&D games, instants being like interrupts or immediate reactions could be perhaps put to use in dire moments or uber-specific situations a spell of truly catalytic proportions
For example, on Mirrodin's Panopticon, rolling chaos will let you draw a card
With this leyline in play, whenever you cast an Instant or Sorcery that targets only a single Creature you control, it copies that spell
Maybe.) Until then, may you enjoy playing Magic without a net
My predecessor, Randy Buehler, wrote an article in 2003 (Banning: Good or Bad?) in which he laid out the devil's advocate position that having to ban cards meant R&D was just doing its job: We could make Magic permanently safe from the threat of having to ban cards if we always played it safe
