Artefacts

Overview
There are two good reasons for collecting the artifacts. The first one is obious - thanks to selling them you can gain a lot of coins. (see the artefat hunting section) But the second reason is more valuable. Artefacts can permanently boost the other cards. Specifically :


 * Miners
 * Crushers
 * Hammers

On each artefact card is information how much increase a based value if you will put that artefact to the card.

Each card has one slot for artefact as a default. You can buy additional slots via hard currency.

Artefact hunting
Each galaxy has own set of artefacts. If you collect all artefacts from the set then you can sell this set and gain 10x more coins than via selling artefacts out of set. Artefact sets are visible in Radar building.
