Hi! I've just seen the Sceptile analysis for DOU that you uploaded... It says in check and counters:
"Ice-type Pokemon: Ice-type Pokemon such as Kyurem-B and Weavile can beat Sceptile with priority Ice Shard, though neither can switch in on Leaf Storm."
Well, Kyurem-B does not learn Ice Shard (and can easily switch in on Leaf Storm). Actually, Weavile is the only relevant Ice Shard user in DOU.
