In that spirit, this isnt about designing cards to win every game, but to make every game better
For example, exalted won't trigger if you attack with multiple creatures and all but one of them are removed from combat
The worst-case counterfeiting scenario might be bad, but it will not kill Magic
If a creature's power is 2 or less when it enters but becomes greater than 2 while Irreverent Gremlin's second ability is still on the stack, you'll still have the choice to discard a card when the ability resolves
Part of the Emerald deck, card number 70/204 costs only five ink to play and can collect two lore when questing, and interestingly it cannot be added to the inkwell to gain ink
For another, even if you dont' have a big enough creature in play, you probably have one in your hand that can do the job
