Elemental Monster TD
Emerald Monster is a battle game where you the player make use of cards to summon beasts. Create your own deck of cards, then select three cards and place them on the battle field. You then select a monster to summon from one of these three cards. Each monster can be made to perform one of two attacks, or if you feel a slight imbalance against your opponent, you can recall your creature and send out another in its place.
