#12 provides an off-brand 4* Unit (Dingo) who is very powerful with versatile builds/comps! He provides a lot, buffs, debuff negation, cooldown reduction, massive combo potential (with skills chaining) and can be built for various purposes. Most importantly though, his combo's SHRED HP. Couple that with a Daydream Joker (Artifact that shreds HP) and you have a beast of a unit. GREAT FOR RAIDS/END-GAME CONTENT/GOLEM HUNTS/ETC.
Hey there, I do not currently have any starter Accounts with both of these Units sadly. As for a price check on it, no current price as I do not own one (I have to factor in a lot of the other components on the Account.)
