So it's good for fun, it has a very strong Synchro summon but it only has one anti effect, the Fiendish Chain. However, if you add an Ash, it becomes really perfect

Well... This deck is my favorite. If you take 3, it's just fun to play. However, if you want to take it for locals, you will need very expensive singles, mainly anti-negate cards, because if the effect of Red Rising Dragon is negated, the game is over. It's a perfect deck for playing with friends just for fun. For locals, you will need to spend around 71 euros additionally for cards, but it will be broken in a way that it will win and cause frustration.
3 Crossout Designator (15€)
3 Triple Tactics Talents (5€ each from Card Market)
3 Ash Blossom (3€ each)
3 Pot of Prosperity (13€)
1 Dis Pater (21€)
4 stars because it won't win on its own in locals
100 stars if you want to play just for fun (of course, the opponent will get a little annoyed but oh well)

As a deck, it definitely needs some extra singles and some links, but if you manage to complete it, it's quite fun to play and quite powerful, unless you play second.
