Card Requests - obsoleting

[xxSkedz24xx]

Skullbriar, the Walking Grave isn't on here. I don't know if that's because it's tricky to code due to keeping its +1/+1 counters, but it's not there and I'm pretty sure many Golgari players are not happy about it

Uba Mask don't see how this got passed over

[Finbez]

The Dragon aura cycle.
Dragon Fangs
Dragon Wings

Risky Move (Onslaught)

Confusion in the Ranks (Mirrodin)
Bend or Break (Invasion)

I apologize if these cards are difficult to implement. They aren't played much either but I want to test them out in EDH.
