Some players like me got duplicated CW Cards from Containment War event, these Cards are currently pointless and untradable.

I thought on a possible solution.
Would be great to add a “TRADE FROM” function, and been able to Trade one duplicated Card from old events for one random event Card of the current event.

I’d rather wait for trading being implemented so you can trade me that arty, it’s the best loadout imo

Yeah, you should trade that to me. I’d give you some really good cards for that Arty.

Honestly, I think you just shouldn’t be able to get duplicates for event cards (and at a stretch, cobalts). In the case of event cards, unless/until they add trading, they’re just cards made of salt. At least with cobalts you can trade them in, though honestly that’s a raw deal too. If the game could just remove drops of a certain rarity or type from the pool of possible drops, the world would be a much happier place.
