The most overpowered cards are powerful and unfair
Full art trainers often become sleeper hits in TCG sets, and the Full Art Serena is a perfect example
Three of the cards (Marker Beetles, Plague Dogs and Yavimaya Elder) cross with another theme of the set, "leaves play" effects
I see it as a higher-agency form of suspend with wider design space, and I find the considerations that players will have to make when choosing whether to plot or just cast a card compelling.
