Toy Dragon SeriesEdit
Fantasy Dragons are more well-known as Toy Dragons due to their appearances, and they're among the most unwanted eggs during REM pulls. That said, their active skills to change colour orbs (of which their main elements are strong against) into Hearts, and their leader skills to reduce damage from two elements (30% for first two stages, 50% for third stage and Ultimate Evos) are pretty useful in their own rights, making them a pretty decent leader and/or subs for Attrition teams, or subs of mono-colour teams. With proper teammates, they can even lead the charge into some Decended Dungeons.
One of the most overlooked advantage for them over Resist Dragons and Legendary Dragons are their lower EXP Curve (only 3 millions over 4 millions of the later two), though stat-wise Fantasy Dragons are inferior to those two except RCV (which Fantasy Dragons' tower over them, making them a help to Dragon teams as well). But one of the downside for the Fantasy Dragons is that their active skill can only be upgraded from Collab Dungeons (except Water/Light ones, which their "food" can be acquired from normal dungeons).
After gaining their respective Ultimate Evolutions, a sub-type is added for them respectively (Attacker, Physical, Balanced, Healer, Devil), so they can now join their respective type teams for coordinated burst attacks allong with Heartbreakers, but note that active skills of will clash with that of .
Since only Jester Dragon, Drawn Joker has its own Survey Dungeon now (as of 6.2.1) and its open time is pretty unstable, if your first draw is one of them, instead of a straight reroll, you can also wait for the result of the second pull.
Though they're pretty common in players' later REM pulls......
