Oh gosh, some actual, legitimate advice
heart
I know mono-red dragons is a little finicky...but you know. You build something and it's yours and that's part of the reason I play it.
I've mostly been running plan 2 & 3, usually with the higher-drops focusing on additional control (Bogardan, Kilnmouth, Flameblast) or making the littler guys more frightening (Moonveil) without giving up dragons. I've actually been dropping many of the higher cost dragons lately...there used to be a few more, along with more an acceleration backbone, but I wasn't enjoying it. Either way, I'd love to hear any ideas you've got.
Also, sideboard ideas. I'd love to hear any you have. I just recently threw one together with Ancestral Grudges, more board clear like Slagstorm, Anarchy for those pesty white enchantment stratagies, and Guttural Response.
