An evolved form that can be layered on Number F0: Utopic Future. It's not a weak effect, but compared to its pre-evolution version, which had the drawback of being difficult to use, it has 3000 RBI, destruction resistance to battles and effects, monster effect negate + control seizure, and has strong elements that are easy to understand. It became a stable suppression card. Don't call me NTR Emperor Hope.
Even before the evolution, the material is heavy, but there are many decks of his that can be produced in modern times. Unlike before evolution, there are 3 materials at the time of emergence, and it does not wear out due to destruction resistance, so it is easy to make use of the 4000 effect of Gagagaga Magician, but since the battle resistance disappears, there is a risk of retaliation. Note.
Note that Decks such as Infernity and Undead Loop, which generate infinite materials when comboed, can also fulfill summoning conditions that do not overlap. Many people target the future emperor for elimination, but depending on his opponent's deck, if you don't eliminate the future dragon emperor, you can build a completely unchanged control board.

The way to put it out is quite special and troublesome, but the quickest way is to put out Xyz from Bahasha and stack FA Lancer?
Although it is a single hit with escape castel, the battle destruction resistance (and no damage) and the effect destruction resistance twice are annoying.
The control seizure effect is powerful, but you can't do anything if there are no monsters on the field, or you can't do anything if you take the opponent in Defense Position, so it depends a lot on the opponent's field.
It can only be captured until the end of the Battle Phase, so it is difficult to use it outside of battle.
For that reason, the effect is strong and the way it is played is also strong, making it a bit difficult to handle well.

Ordinary material designation looks very heavy, but it's actually not a big deal because it can be done at level 4 x 2.
It has a double attack effect that can't be direct, but the conditions for increasing the RBI are strict, and it's hard to extend it until you can fight a low-ranking attacker instead of aiming for a high RBI.
It is possible to rely on the numbers issued by the other party, but even in the days when Xyz was the world of Extras, it was difficult to rely on the other party's Numbers. So I can't use it at all.
Even so, it had the advantage of being a card that could steal a lot of his LP in a 4x2, but with the same summoning conditions, he would have to put a double-up chance in his deck, but he would quickly turn to murderous intent. It was a big headwind that the double that was done came out.
