Losing abilities (Jebus is going to hate me for this)

[Jacob Orlove]

I know they fixed Opalescence/Humility, but what about Titania's Song/Mycosynth Lattice? How would that work? And what if you have Song/Lattice out and cast Humble on either one of the two?

Also, is there still a rules issue with those cards that switch power/toughness and have the "effects that would affect power affect toughness, and vice-versa" text?

For Song/Lattice, read this.  You may have to scroll down a bit.  After reading that, let me know if you need anything else clarified.

Also, is there still a rules issue with those cards that switch power/toughness and have the "effects that would affect power affect toughness, and vice-versa" text?

What rules issue are you referring to?  Can you be specific?  The only thing I can think of is that it can be confusing to some people, which as you know some effects are capable of.
