Eggs are used to help the batter set,
Eggs keep your cake together without eggs your cake would fall apart.
Because in a sponge cake, there is eggs.
The eggs are to hold the cake together and it's the bicarbonate or baking powder that causes the cake to rise. Try 2 teaspoons of flax powder mixed with half a cup of water. This has great binding properties and is high in fiber and Alpha Lipoic Acid (ALA), an omega-3 fatty acid. A mashed banana is also a good substitute for eggs.
Eggs are the glue that holds a cake together.
Eggs are very important to a cake. If there are no eggs at all, or not enough, the cake will not hold together. After baking, it will crumble and fall apart, as eggs are the main binding agent in the cake batter. Eggs also add moisture. Too many eggs will result in a goopy and dense cake, while too few eggs will result in a dry and floury-tasting cake.
A cake will last longer without ingredients such as eggs and milk. EG: in the war soldiers were given the anzac biscuits as they could last long periods without perishing. The cake may also be more crumbley without eggs, as eggs assist in binding a cake.

It will be slightly less moist, and may crumble or be a bit mroe dry and hold together less well than a cake made with all three eggs. But since two out of the three were still used, it probably won't be that bad.
