Reoin+Bottaries ftw. Limited space is interesting, but I feel like it really punishes longer-growing plants pretty harshly in the late game. Rain is the best water card by a long shot, obviously. I can't imagine any build for this game that doesn't start off with Sproccoli and then pivot away from it once per-turn energy is 'enough', nor one that doesn't have at least a third its cards be Reoin. That would probably be a bad sign for strategic depth, but this game was made in three days so honestly it's impressive it's as complete and strategically interesting as it is.
