whenever you attack with two or more non-gideon creatures, put a +1/+1 counter on each of those creatures.
+2: until end of turn, gideon, the oathsworn becomes a 5/5 white soldier creature that's still a planeswalker. prevent all damage that would be dealt to him this turn. (he can't attack if he was cast this turn.)
−9: exile gideon, the oathsworn and each creature your opponents control.
