Attackers in this Dark Sun realm can only be flyers or earthwalkers. Both champions and allies are affected by this. Since this restriction does not affect icon types, it can be used against almost any deck configuration. Unless your opponent(s) have several earthwalking champions, Waverly (238/1st) can make this realm almost impossible to attack if you attach a holding that prohibits flyers.
In addition, Lake Island is also capable of defending itself as a level 5 monster champion if necessary. Any card that helps or hinders this type of card will affect this monster champion.
It is not recommended to play Volcanic Eruption (64/RR) when you have Lake Island in your formation since this realm can only be attacked by earthwalkers.
