Hitting Myself

[Gidoza]

I imagine I CAN do any of the following, but I just wanted to make sure...

1. Can I curse myself? (unless, of course, the card specifically says OPPONENT on it)
2. Can I use monster enhancers on a monster I am fighting? And other potions?
3. Can I toss in a Wandering Monster or Undead Monster in a battle that I myself am fighting?
4. Can I use a variety of abilities or other cards on myself, if the card wording made that possible and appropriate?

In a slightly related theme...

A. Can I use potions and the like to boost my own strength when I am already winning the battle? (reasons to do this: stuff like getting a 2nd level from Orc ability, or what have you)

B. Well, this isn't entirely related, but is at least associated with combat. If someone tosses something like "Death" on a monster for any reason, and that was the last monster in the combat, is it already too late to toss in a Wandering Monster or an Undead Monster at this point? How about "Dead Broke?"



Thanks!
