>>47942948It literally depends on if you're good at the game.
Are you an admitted shitter that just picked up Greninja but has hardly any knowledge of the fundamentals of the game but wants to do damage anyway? Go Shuriken (or better yet,
just play Cinderace since it's even more braindead than Shuriken Greninja, but more efficient at damaging)
Do you actually know how Greninja's passive works, how his ranged attacks differ in damage and purpose to his melee attacks, recognize how to use Empowered melee dashes efficiently, recognize Enemy and Boss executeable HP levels, and is also aware enough of the map and situation to be able to determine WHEN is it convenient to engage? Then go Surf. Otherwise you'll just end up feeding like a Yasuo shitter and embarassing yourself and all your kin.
