Crests are powerful items which provide large and unique buffs to certain Pokemon. Here are my recommended movesets for each crest Pokemon. Shoutouts to Falirion for compiling the Crest effect guide and all of the Rejuvenation devs for the great game! Check out the Item Location Guide to see where to get each Crest (you can't get them until near the end of V12). The intention of this is not to replace the Crest effect guide, but rather to explore the viability and uses of Crest Pokemon.
