I have noticed that Red Card Deoxys-D is very popular on the suspect ladder. It definitely fares better against Aegislash than Deoxys-S which may make it the better hazard setter of the two. Of course, we have no idea what a ladder with Deoxys-S but no Genesect or Mega Lucario looks like because it was all or nothing on the ladders for this test. Whether some of the Deoxys-D are replaced by Deoxys-S if / when Mega Lucario and Genesect are banned remains to be seen, but I don't think we should ban Deoxys-S right now based on what we think the new metagame could theoretically look like. My guess is that both Deoxys forms will see a spike in usage after this, and I hope that the suspect council will not hesitate to retest Deoxys-S along with Deoxys-D if Deoxys HO gets out of hand like last generation after Genesect was banned.
