Literally Anything

When casting Literally Anything say the type
(artifact, creature, enchantment, instant, land,
planeswalker, or sorcery) and describe the details
of the card to all opponents. Opponents can
counter this spell by effectively arguing that it
is over-powered for at 10 mana-cost card, or
that it is out of flavor for it's chosen color.
"It's a... 8/8 red elf... with menace and... um..."
"Elves are green, not red!"
"There's no rule saying elves can't be red!"
