Xeno'jiiva, Young Dragon

Flying

When Xeno'jiiva enters, search your library for up
to three Dragon creatures, reveal those cards then
put them into your hand, then shuffle your library.

Dragon spells you control cost {r}{g}{w}{u} less to cast.

Whenever a Dragon you control dies, put a number of +1/+1 counters on Xeno'jiiva equal to its mana value.
