Their base stats are 2500/2500, meaning they have a decent standing chance against decks that dont synchro.
Hmm... Also, Wisel Infinity can negate spell cards once a turn.
If you negate the opponents field spell card, you can protect yours.
Sin Dragons have an effect that will cause them to self destruct when there is no field spell...
Which fufils the summoning requirements for the Machine Emperors!
Also, the Sin dragons tend to be larger, and hence more prone to being destroyed by effects...
