#5 - Glimmer, the Brass Dragon (Draconomicon chase, 16/25)
Glimmer is a flyer and an earthwalker, a pretty rare combination (I can't think of another Spellfire champion who has both abilities off the top of my head...are there any?). If Glimmer wins a battle, you can return one magic item or artifact from your discard pile and attach it directly to him - and that's on top of the instantly-playable spoil you will also be collecting. A neat little power, and one that gives Glimmer the edge over Dregoth, Sparkle, and the other dragon champions all clawing at the #5 position on this list.
#4 - Sleet (Draconomicon, 39/100)
Borys is rated higher than Lareth because of his versatility. He can use wizard spells, cleric spells, and psionic powers. He's a flyer. And (since he is in direct competition with Lareth for this #2 position) Borys is also immune to Midnight, Goddess of Magic's spellcasting ban, since he's a monster and she can only affect wizards. Borys (like Lareth) is also immune to psionic power cards such as Inflict Pain and Drain Will. All things being equal, I say Borys's extreme versatility is worth more in your pool than Lareth's immunity to all offensive cards. He gets the #2 spot.
#1 - T'chaar, Dragon of Flame (Draconomicon chase, 1/25)
Unlike spots 4-3 and 3-2, there was never really any doubt in my mind as to which dragon champion would be #1. T'chaar is one of the best attacking champions in Spellfire, period. In TAV, where you only get one attack per turn in most cases, the Dragon of Flame is even more awesome. T'chaar is a flyer, and he can use any offensive card. Doesn't matter if it's an unarmed combat card, a thief skill, a psionic power, blood ability, or spell. If it's offensive, he can use it. This gives you an incredible amount of choice as to which cards to hammer your opponent with during battle. As for T'chaar's "downside" (defensive cards are doubled in level against him)...well, that's not much of a downside.
Next time: A noble piece of cheese.
