Do these erratas work for the Future Fusion cards?

[Noromoir]

I haven't heard much good about these cards as of late, so I figured I'd fix them (also Overload isn't really Future Fusion at all). Do they need any more changes, or are they good now?

Future Fusion

You can only control 1 "Future Fusion". Reveal one Fusion Monster in your Extra Deck and send, from your Main Deck to your GY, Fusion Materials listed on it. Until your next Standby Phase, Monsters sent by this effect cannot be targeted or affected by Spells/Traps or Monster effects, and their effects are negated. During your first Standby Phase after this card's activation: Fusion Summon 1 Fusion Monster with the same name as the revealed card. If this card or the summoned Monster leaves the field, destroy the other card mentioned in this effect.

 

Overload Future Fusion

(This card is treated as Future Fusion while on the field)
You can only control 1 "Future Fusion". If this card doesn't have a target, you can reveal 1 Fusion Monster in your Extra Deck and send, from your Main Deck to your GY, Fusion Materials listed on it. Until your next Standby Phase, Monsters sent by this effect cannot be targeted or affected by Spells/Traps or Monster effects except this card, and their effects are negated. You can activate only one of these effects:

● During your first End Phase after this card's activation, if the revealed card was a DARK Machine Monster: you can target one Fusion Monster in the Extra Deck with the same name as it and banish the Monsters in the GY sent by this card's effect, then Fusion Summon that target.

● During your first Standby Phase after this card's activation: Fusion Summon 1 Fusion Monster with the same name as the revealed Monster, and if that Monster isn't a DARK Machine: target that Monster at the activation of this effect.

If this card or the targeted Monster (if any) leaves the field, destroy the other card mentioned in this effect.
