The impressive part is that the fonts actually look acceptable with the proper font and everything. That part is quite impressive.
As for the Yugioh actual text part, they really don't make too much sense in comparison to the actual rulings to the game... I suggest you to learn a bit about game mechanics and the way how most existing cards decide to word effect, then do some editing.
But it's impressive, finally get to see some card pictures that are not done with that yugioh card maker thing >_< It's not perfect, but I think it's acceptable quality.
These are good, but like Frostweaver, I think you could've tried to keep the effects co-ordinated with the actual Yugioh Effect Styles. Good job though.
When they need someone who can defeat the evildoers, but at a reasonable price, they call me. There are some who say I cannot compete. I say, it's not a matter of competition, it's because Wizards of the Coast said so.
