It takes some practice, but you can remove the foily cover from any card and then paste it on a regular one.

Leave the card soaking in some water overnight, and try to peel it in the morning; let it dry and use some glue

I like how that card just uses a bunch of cards...
CONTRACT FROM BELOW WAS DISCONTINUED IN REVISED, IN ADDITION TO THE FACT IT"S NOT A CREATURE-BIRD...
so im going to assume it was a proxy, using some sort of computer graphics program -ahem- photoshop -ahem-...

You didn't read my post: you soak a foil Sootfeather Flock in water overnight, and the next day you peel the foil cover off the card and paste it onto a Contract from Below.
well, then there is the itchy little fact of casting cost, and the obvious proxyness, due to the lack of foil directly around the text box (unevenly i might add) and the picture (even more so) and also im sure a ghost of (c)1994 Douglas Schuler would appear in the bottom left corner, and then the whole "hey, may as well ruin a Contract from Below." thing too
