For Phase 4, when taking 2 cards from the supply and placing them in your hand (behind all your other bean cards), wouldn’t your hand fluctuate in size? Isn’t your hand always supposed to have 5 cards? Depending if place on or twomcards in Phase 1, and/or if you gift a card from your hand to your opponent, you could end up with no cards at some point in your hand (or a bunch). Am I not understanding this correctly? Haven’t actually played the game yet so just theorizing here and I’m not getting it.
really sounds like you havn't played the game yet. ;-)
There are completely different developments of your hand cards during the games. Sometimes you go down to zero, sometimes you have 6, 7 or 8 cards in your hand. Depends of some many things. But usually the number of cards in your hand get less.
Drawing 2 cards at the end of your turn ensures that you will have at least one card at the begin of your next turn (as you only can loose a card by giving it as a gift in your opponents turn). So in any case you have to plant a bean card from your hand in phase 1 of your next turn.
Try the game, just play a few games. You will see that drawing these two cards makes sense finally. ;-)
