Rex drops in Chromium?

Is Rex still dropping decently? I'm considering trying to get him. Haven't made a final decision as of yet. I'd try to unlock through Chromium and then shipment up.

I've opened 3 mega chroniums and didn't get a single shard from him.

I bought several packs last month - dropped me a 4 star Rex and enough shards to 5 Star him - took my about 10-15 packs...
