A plane card is treated as if its text box included "When you roll {PW}, put this card on the bottom of its owner's planar deck face down, then move the top card of your planar deck off that planar deck and turn it face up." This is called the "planeswalking ability."
The Hippodrome
A creature that would assign 0 or less combat damage (due to having power 0 or less) doesn't assign combat damage at all.
Creatures may have negative power. For example, a 3/4 creature that gets -5/-0 becomes -2/4. The total of its power and toughness is 2. It would need +3/+0 to raise its power to 1.
