Bloodforged Battle-Axe if you want to drop twenty bucks.

Bruenor's ability works on all of your creatures so maybe one or two of your creatures could be unblockable? I like Soltari Visionary or Commander Eesha . Or use Spirit en-Dal to Forecast.

Balduvian Rage to replace Enrage .

Love the Jitte - Dragon combo

OK, you can equip Lightning Greaves to Inferno of the Star Mounts for a +2 power. If that puts him at 20 you you trigger the effect. Then you move the greaves back and forth between any other creature for zero mana for infinite damage

carpecanum I actually did consider something like that. I originally has Skullclamp in the list for exactly that purpose. The problem is, if you look carefully at the way the ability on Inferno is worded, it doesn't work. The ability ONLY tiggers if it reaches 20 power as a result of the activated ability. So you could do it once (get him to 17, equip, use the ability to get him to 20, unequip, activate 2 more times to hit 20 again). After that though, the power would be too high and you would need a way to reduce it (like -1 counters) before you could do it again.
