Duel is a bit OP. Just go full AD runes, stay safe in your top lane until level six, then gank mid and Duel the AP carry. +15 damage. Then repeat every 70 seconds. After 10 minutes, say you have done 8 of them (all resulting in a kill, 5 seconds of free damaging your enemy is much), you have 120 bonus attack damage. 3 Phantom Dancers, and it's gg.

But the idea is nice. Maybe grant the winner full life, or something like that. And how would it work with Tryndamere? Because his ult is ALWAYS castable, even when silenced/suppressed/stunned/taunted/etc.
