#5 - Glimmer, the Brass Dragon (Draconomicon chase, 16/25)
#4 - Sleet (Draconomicon, 39/100)
Borys is rated higher than Lareth because of his versatility. He can cast wizard and cleric spells, as well as use 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 at all.
Next time: A noble piece of cheese.
