As is so often the case, water is underestimated, as it is difficult to field a good team with many expensive cards in the low mana range. As soon as it is over 20 mana, so my personal impression, you are almost unbeatable with the right technique against the right opponent. Helpful here, the hero abilities speed and armor.
I have set up an order here, which I myself use very very often. Of course, without level or the like. Especially the last card is hard to get currently.
Of course, this deck is only recommended with normal rules and against an opponent who plays with melee or ranged combat, not against magic.
Optionally, this combination can be used at 23 or 24 mana. What is your favorite water deck in this area?
