I love plain e-Series and EX reverses (i.e., from Expedition, Aquapolis, Skyridge, EX Ruby & Sapphire, EX Sandstorm, EX Dragon, and EX Team Magma & Team Aqua). I think I appreciate them so much because they remind me of beautiful Silver Age MTG foils growing up. I find their simplicity satisfying and mesmerizing.
I know that they are considered the most boring reverses of the era by many, but I honestly can’t get enough of them.
