Since Planisphere creates and attaches to a body on entry, it essentially functions as a creature
Its a useful mix of options, because it means youve always got a good one to choose whether you need an extra body or a little more power
It helps a lot that the set is also a huge amount of fun to play, and being able to enjoy building decks around the mechanics in either a draft or Commander is a surefire fun time for everyone involved
Many players would agree that the deckbuilding side of MTG contains as much fun as the actual gameplay Im certainly one of them
It's also close to a one-sided wipe in a very popular archetype, though obviously if any of your foes bring +1/+1 counters too, its strength goes down significantly
Note that if everyone always played according to the current floor rules, Sindbad would not be on this list
