Relics you get depend on the size of the hit(s) (the amounts of units lost by all the players engaged in the battle(s)). If you hit a heavily defended Presidio with 100M off, you're bound to get a better relic. If you keep sending roughly the same amount of units to prizes, you'll keep getting the same relic (and the one you showed is a very common one to get there).

In short: it's a feature.

is this on prizes?

They are pretty predictable there.

If you want the good stuff PvP will likely find it for you.

When it comes to relics, there is no such thing as "good stuff". Just stuff that sucks less. IMO, no relic is worth losing units over.

Hi there! The thing is that Relics drop by the random. However, you have more chances to get a good Relic by participating in PvP battles, as it was mentioned above.
