As long as your hand consists of only Dragon cards, you have no maximum hand size.
{r}{r}:Reveal cards off the top of your library equal to the number of Dragons you control. Then, Qvejurus deals damage to any target equal to the number of dragon creatures revealed this way. Put all Dragons revealed this way into your hand and the rest onto the bottom of your library in any order.
