Tacticus

Unlocked couple more characters. Most of the shards came still from Anniversary Event.
Unlocked Patermine, last shards were from Guild War. That’s the most expensive Genestealer, and the last I needed.

Unlocked Kharn, another powerful Legendary. Last shards from Guild War. One of the most damaging characters in the game. Also, he’s a berserker, so if there’s no enemy character nearby, he will attack and most likely kill one of yours.

Cyrus, again most shards from anniversary, because I had to spend them on someone, and the last few from a random code gift, out of all things. Not useful.

Aunshi. Once he was mandatory, as the ability to use Active skill twice is very powerful. Now I think the meta has moved on, but hey, still not bad.
