I've been thinking of this sort of thing, only it'd be
1188
0|0
On hit, target dies
(if ununpgraded, deals 99 non-spell damage to owner on play)
Issue: Byt. But I don't want to have an "on play clear your board" effect so I'd increase Byt's active cost to 1. Maybe reduce self-damage of Byt to 2. Or leave it be
If it costs less than 1188 geores will be able to afford it even with diss up. Not something I'm want to help
The hassle with these sorts of things is either it's the best card or the worst case in any given matchup. Very little room for flexibility, which means very little interaction. Either you setup infinite quanta or you don't. The 0|0 version changes things to involve more pieces, which means more potential for disruption
