While the "ease of flipping" category is, in large part, a product of the number of defense counters on the battle (battles range from three to seven defense counters, and a battle with three defense counters will be much easier to flip than one with seven), it also takes other factors into consideration, like whether the battle makes creatures (if so, we can use them to help defeat the battle, making it easier to flip) or whether the battle acts as removal (which can get a blocker out of the way, making it easier to attack and defeat the battle)

Ertai Resurrected Obscura Interceptor is sad that Ertai Resurrected is a much better version of it, as it completely denies threats and also cleans the board of resolved ones
I remember I was 7 when they launched here in the UK, I still remember opening my first Base Set booster pack, I even recall that it was a Blastoise art pack and I pulled a holo Poliwrath, from that moment I was totally hooked and so excited to find and collect all of the cards, not just to own them, but to see the artwork, that sense of discovery was incredibly rewarding
