Psyringe - added some cards with the nofizzle ability.

Question: I also tried to code Root Sliver (LGN) with the line "auto=lord(sliver|stack) nofizzle", but this didn't work, Slivers could still be countered. Did I choose a wrong approach, or is there a limitation of the lord ability with regard to spells on thee stack?
