Guys I need an advice on the equipments for low TH

I'm at TH 11 with only 1 epic equipment, the magic mirror. I bought the event pass to get the equipment in trader shop. I'm not into the strategic rushing or rushing at all, so please consider it when reply. I should take the Dark Crown and Spiky Ball now or wait for the Clan Event? I feel like should get those 2 and try to get other equipments that I don't have in the chest, I know that the chances are low but anyway. What is your toughts about this?
