Re: Rate a beginner's deck
If you want mass removal, I'd definitely go with Nevinyrral's Disk in this sort of deck over Chain Reaction or Pyroclasm or Volcanic Fallout. Chain Reaction is rather unreliable (and frankly, I think it sucks :p) and Pyroclasm and Volcanic Fallout only kill small creatures (like your goblins!) and you shouldn't have much trouble in the early game with this deck, anyway; it's the big monstrosities like Baneslayer Angel or Terra Stomper that are going to wreck your day. Disk can also get rid of enchantments (which red cannot do at all normally) and artifacts (thus you can probably remove Pillage), plus you have no enchantments and only 4 artifacts.
