1, Cards played by the Maythm buff at the start of the turn doesn't trigger the Energy gain and +1 Rhythm from Rhythm. Otherwise, with the Necronomicon relic, Rhythm 2, and Hold Note buff, the second 2-cost Attack card played by relic also doesn't trigger the Energy gain effect from Rhythm. If this is a feature, I can live with that ,but maybe more accuracy desc? At least in vanilla sts, similar "Play a card" desc buff like Panache or Storm doesn't specified must play by hand.

2, Playing two Echo cards in a row does not gain Echo 2. However, playing Echo followed by Echo+, or playing two Echo+ cards in a row, correctly gain Echo 3 and Echo 5, as expected.

I translated this mod to simp Chinese, and it works fine for me. How can I sent the lang file to you?
