my thought is that with merry hopping up and clogging your hand, the 35 might be too big. i try to run bouncing hobbit decks between 30 and 32 cards. seeing as daddy two foot and
birthday present are both unique, and do essentially the same thing for the same cost, heres what i would do:
playtest to figure out how well the deck is cycling. if its REALLY bad, you might have to cut 1x of each and then some. if its mostly good, but could use some thinning, figure out which is more useful. and cut 1x of the other. daddy two-foot is nice because its harder for your opponent to get rid of it, and it give you the
unheeded in the maneuver phase when you know what you are up against. on the other hand,
birthday present is useful, because you can get all 4x into hand if you are willing to drop the burdens.
but thats mainly what i'd cut. 4x
unheeded should be enough to hold you until you can get one of those in play.
