Earth Elemental is the one which is a must use card in snipe mode. With 8 heath +1 or 3 health depending on the summoner and monsters you choose this card is really cost effective. If the enemy use sneak attack monsters then you can just put this card at the back and it will las longer because of the high health and healing ability. This card also has 3 range attack which can be increased by using a summoners who gives 1+ range attack to all friendly range monsters. In terms of speed it's the slowest card.
