There are a few edge cases worth mentioning

His favorite card of the month is Growth Spiral

Free to do but only sorcery speed and also only able to sacrifice X-1 things where X is your number of things

Something along the line of a scannable code on cards to verify authenticity would get the job done, but implementing the program would be costly, and it wouldn't help with all the cards that are currently in print (barring some sort of mass-exchange program, which would be even more prohibitively expensive)

Should you cast it for this cost, you wont really be spending any mana, since The Great Henge is a mana rock that taps for two green

It deals 13 damage to each creature in play for a staggering nine mana, but that cost is reduced by one for each creature in play
