Note: Here are the skills that Scud (DSOD) possibly acquires.
When you deal battle damage to your opponent, you can deal another 50 points of the damage to your opponent in additional. This Skill will not be activated when your opponent's Life Points is 1000 or below.
Even then it would be bad. It doesn't matter if you deal 1000 or 1050 damage: 4 Attacks will be enough to decrease the LP to 0.
The only reason to use this skill I can imagine is the following: You have a deck that can easily deal either 3950 damage with 2 monsters or 3900 with 3 monsters. So, this skill would turn it into an OTK deck. But even then Beatdown / The tie that binds would be better
