one piece uno card game Cards regardless of what the top card of the discard pile is Ensky UNO (One Piece)

World Shaper One of my favorite combos to run in Commander is World Shaper plus Obliterate for the ultimate Plague Wind effect

Same thing here, less is more

Apocrypha Plane: Oblivion At the beginning of each players upkeep, that player exiles a card at random from his or her hand

Each effect feels more tricksy than backbreaking while not necessarily the best of the Confluences (Id take Mystic in a vacuum), the flexibility you get for the four mana is hard to beat

They are simply true

You can then take two of those cards and add them to your hand, not drawing, which is important in case youre looking to get around draw triggers
