Long before I began playing Star Realms, I played an unhealthy amount of Magic: the Gathering. It has always been my favorite thing to counter a spell and shut people down. I could never actually finish someone off with aggressive decks, and they were lacking in choice and card advantage. I’ve always loved to draw extra cards and to come back from behind. So, it’s no surprise that I lean towards blue/red decks in Star Realms, with lots of bases. For a long time, I didn’t touch green cards if I could avoid it.
Furthermore, back in the days before Colony Wars, what is now “top row” was the “big deck” format for a very long time. I felt very confident in that format, and still believe that the top-tier deck is one revolving around bases/scrap/life gain, and that aggro decks are considerably weaker.
