Consensus is that Paleozoics are at there best when it is easy to mill a notable number of them to the graveyard. In addition, the Frog engine has always been at home in the deck. You see where I'm going? Let's play all the good cards.
The Sprights and Frogs easily allow a first turn Toadally Awesome. The Tearlaments set up your graveyard, and Merrli being a level 2 aqua is incredible to access Spright combos. But, why play this over pure Spright or pure Tearlament? Trap cards. There is nothing more debilitating to combo decks than setting three after setting up your Toad and possibly even a Dragostapelia.
And you will never lose to Mystic Mine ever again.
