Hello people, the problems are the following:

* Let's say I have a 2/2 creature. Then, my friend puts a -1/-1 counter on it (a counter that doesn't dissappear at the end of the turn, it remains), so now it is a 1/1 creature with a -1/-1 counter on it.

Then, I decide to put a +1/+1 counter the same creature... Is it now a 2/2 creature with a -1/-1 counter and a +1/+1 counter on it? or do the counters replace each other and turns out to be a normal 2/2 with no counters?

* Let's say my opponent has onto his battlefield Crumbling Ashes and Necroskitter. On the other side, my side, I got a Vorapede with a -1/-1 counter on it.

In his unkeep, Crumbling Ashes destoys my Vorapede. Does my Vorapede return to my battlefield with undying? Does it return to his battlefield with undying because of Necroskitter? :S
