Help improve my mtg (magic the gathering) mono red deck?

All you really need are more playsets. Figure out what cards work the best together, drop the ones that don't and get playsets of the good ones. 4x Lightning Bolts is a thumbs up though. :) In my red deck I run 4x Prodigal Pyromancer, 4x Lava Axe, 4x Dragon Whelp... etc. It's mostly a burn deck with weenie creature support.
