Ok, now I have less salt on my system, so I have to ask. Why Ultimatebrakiomon and Yataramon were the ones moved to other eggs and Ouryumon the one you have to obtain through evolution?
Ultimatebrakimon is a high Attack and HP digimon that is good for PVP Def, although now is common to see 4 or 3 LRs in defense team, and Grandis is soon to be a part of those teams. Its main skill is good for mono, but is far from being the best choice for that: Crossmon (converter), Insekimon has better defense and is a better leader, BvD just better overall.
Yataramon is a +2 on 3 turns with High attack and low def (even less relevant on Def teams now). You don't get a real advantage with him on a mono team (Blitz and Ancientsmega are a better comb), Ravmon is better for the attack buff. And the others +2 on 3 turns avaliable are just better.
So they are the less useful SP+ of the previous Flash eggs. I personally see them as a nuisance now that they are on FPs eggs and GSP eggs, hurting my chances of getting good SP+ mons (or LR) on those eggs. Ouryu was the best of the 3, and for me he is better than Holyangemon SP+ because even if he has less defense, he has better supp stat and that's one of the more important stats of a converter, even more if we see the new Def System on PVP.He also was easier to combo, since you can get BvD on FP eggs, and from what I know, there aren't many Dark shufflers(?) other than P&G that you can't get anymore.
PD. I could not care less for Slashangemon.
