Some cards are showing phyrexian mana incorrectly.

Birthing Pod Shows it correctly.
Norn's Annex does not.

No white Phyrexian Mana symbols display properly.

for me it is displayed correctly. Can you explain in more detail what seems to be the problem for you?

Yep, the white phyrexian symbol was not correct. Fixed it now, it should work (if you still see it badly, Shift-refresh the page or clear the cache, the image sprite is cached).

oh... on the Page of the card ...I see...but its fixed now ;)
