Mox Amber The best features of Mox Amber is that its a card that you can cast for free, and it generates mana if you control a legendary creature
Its not like there arent enough answers to the card type, what with attacking it, discard, burn, countermagic, Pithing Needle and variants, Oblivion Ring and variants, Vindicate and variants, Vampire Hexmage and variants, outright killing the controller, playing in such a way as to minimize its impact, and legend-ruling it with your own copy all being options available to players [and designers]
Witness was never a good tempo card and it isn't a great value card in green ramp either
Screenshots from phones or low-resolution game captures tend to look soft or pixelated when printed, especially on a premium card where the print quality is otherwise high
It can also change if a second discard spell can hit the rebuy but not the main spell
