Yes, I know you want to re-use this, but it would probably be better for the game as a whole to remove the bounce effect. If your alpha strike doesn't kill its target, then bouncing the aura can only lead to despair or frustration. If it does kill the defender, then you either don't need the bounce ability, or you've just painted a big target on your dome.

Hmm. Lure doesn't have to go with alpha strikes - it can be used more like a "surgical strike". This is more useful in that kind of case. This is very similar to Nemesis Mask, but rather more expensive; the flip side is it works well with the set's enchantment triggers.
