[2021] I'm a boomer who climbed from Gold to D1 with a double support strategy I created and I made a video describing it

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 :(

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.
