Sidon, Zora Prince

Sidon, Zora Prince enters the battlefield with four quest counters.
At the beginning of combat, you may tap Sidon
and one other creature, if you do, remove a quest counter from Sidon.
When you remove the last quest counter from
Sidon, search your library and/or graveyard for a
card named "DivineBeast: Vah Ruta", and put it
onto the battlefield.
