Wow, lots of great advice Aaronock. You're right, my deck is an Emeria Control deck (is that its official name then?).
The cards you listed should be pretty easy for me to get, aside from the Elspeth and Paths. >.< xD And the card you're thinking of (the 40-Life winning one) is Felidar Sovereign.
You're right though, this deck does lack speed (which seems to me to be the problem at the moment) to beat some of the faster decks.
I'll try these ideas out and see what happens. Thanks a bunch.
