So uh... I regret to inform you that Shard of True Ice not giving minion penalty is not intended. It was fixed recently, but not as a result of this video. Sorry for nerfing your strategy :(

One of our designers accidentally removed it for Shard only while doing a rescript :(

Well, that explains what I just started looking into. Thanks.

Would you happen to know which patch this was introduced as a bug, too, btw?

Around March sometime I believe. It's not really a common strategy to cs with support item, so probably took a while to catch it.
