This is something that I've been wondering when I duel opponents: Do global cards effect my opponent also? For example, if I cast a global card that increases chances of getting super pips, will that only effect me, or everyone (including my opponent).
Just like PvE (Player vs. environment) it affects both sides. If you cast Wyldfire, your opponent can do more damage with fire. If you cast Doom and Gloom, both of you will have trouble healing. And so on.
wow, im impressed that my name still is up on this post after three days and I never made a post. Well I guess I should just make one to hopefully get the last poster name changed if someone would post after me. :)
I have to agree with all those before me on this thread, it affects everybody.
