Feedback on Spell Chess--confusing naming and description

I have two issues with the rules text of Spell Chess that slowed my learning:

1. The Freeze spell has the warning "Be careful—any piece, including your own, will freeze if it enters the spell area." "Enters the spell area" seems to warn against moving a piece into a freeze--but this never matters. If you move a piece into a freeze area, the freeze area will be gone by your next turn, so it doesn't matter. Instead, the warning should be about casting the spell on your own pieces. It would be clearer to say: "Be careful--the freeze spell freezes all pieces in the area, including your own."
2. The name of the "Jump" potion is bad. When you think of a "jump" spell, the assumption is that you cast it on a piece and it helps that piece jump. But in Spell Chess, you cast jump on a piece to enable *other* pieces to jump over it. I think a better name would be "ghost" or "disappear" or "blink" or  "phase out" spell--these would imply that the piece you cast it on goes away for a turn, which is effectively what does happen to the piece effected.
   
   The "jump" name also gave me the expectation that I could cast it on a piece next to my King and the King could jump over it. But this is not the case. Again, I think renaming the jump spell would make it clearer.

Its called jump because of clash of clans
