This is very odd. If you remember yesterday I posted how I got the same 3 reward cards.
Today it happened again and that seems to be either very odd or a bug.
The above image is from yesterday rewards. If this is a bug I wonder if someone else has seen it. If the development team is aware of this or how can you explain the statistics for this set of reward cards popping 3 times and 2 days in a row. From my point of view it is clearly a bug and something to be aware of, imaging if a very rare card was given this way decreasing it's market value a lot. Anyways I also wonder if that card is worth leveling up.
