The approach differs depending on whether you are creating original cards, reselling existing ones, or doing a hybrid model
For example, in the fake Wartortle, the Pokmons name is spelled incorrectly as Wartortleh, the word flip is spelled filp, and the word turn is spelled trun
There is also tension between trying to match mana values, presumably at lower points on the curve, and using the Treasures to power something out
This resulted in 1st Edition runs sometimes launching simultaneously with, or even after, their Unlimited counterparts, effectively making them pointless
