The idea came from opening a pack with Leaf-Leap Guide. I liked the idea of a Frog deck. Thanks Wizards for making it possible.

All of the cards have "enter the battlefield" effects so the idea is to keep the battlefield bogged down while building the strength of Leaf-Leap Guide. Leaf-Leap Guide allows me to unsummon a creature at the end of my oponnent's turn. Early game it's Pond Prophet to get more cards when needed. Dour-Port Mage, Skyskipper Duo and Lilysplash Mentor fill similar roles in bouncing cards. Roaming Throne and Virtue of Knowledge double the triggered effects such as drawing more cards, tapping and stun-countering enemy creatures, or making creatures in-hand cheaper with Fountainport Charmer.

Enemy tries to kill a creature of mine? Unsummon, Run Away Together, Leaf-Leap Guide, Dour Port-Mage, Lilysplash Mentor.

Stony Strength and Frantic Strength are good for defending or getting that last couple of trample points in.

Bouncing Long River Lurker to allow one of my frogs to be unblockable has won man a match. Add in Roaming Throne or Virtue of Knowledge to have multiple Unblockable 5/5+ creatures is beautiful to see.

Remember, every time a creature comes into play that I control while Leaf-Leap Guide is in play, it is +1/+1 stronger. Even if I have to unsummon Leaf-Leap Guide the strength remains. Also, remember that Leaf-Leap Guide has Vigilance so you can attack with it and later still use its ability.
