All Monsters in Eggs
So at least every normal player who's saving silver can dream of monsters as verte or felicity even if the chance is significantly low.
Otherwise you will never have a chance to get those monsters without spending 100€ for each of them. This is just a too high amount of real money for a small smartphone game.
Some might say it's unfair because they already got those monsters for real money.
But what should the ones say who bought a second draco?
As i said the chance can be really really low but at least there sould be a chance.
