作者R. Eric Reuss的原话
Spirit Island was originally designed with a 70-some-odd card Minor Power deck and "Draw 4 keep 1"; the slightly lower variance on core-game is an artifact of splitting the game into core + Branch & Claw.
If a future expansion adds another big batch of Minor Powers (so the deck goes to ~130 cards or something), I'll probably recommend going to Draw-5-choose-1.
基于70张设计的“抽4选1”,要达到130张需要core+1+2+3一起玩才会有这个问题,作者推荐这个时候“抽5选1”
