I think I got the flavor of a red/black Planeswalker right this time...? :S

If you control a face-up Tuner monster, you can Special Summon this card from your Graveyard. If this card was Summoned this way, remove it from play when it is removed from the field.

Instant Synchro is just so much better than Instant Fusion. Even though it has fewer targets, you get to reap the effects of Cosmic Fortress Gol'gar, Armory Arm, Turbo Cannon, or X-Saber Wayne. Ugh, I'd hate it.

Quillbolt Knight is a bit overpowered. If anything it should double only original ATK like the original Speed Warrior, but having it double ATK increasing effects as well as the potential to target ANY monster means it's very OTK material, especially given how easy Quillbolt is to summon...

 

[Cirrus]

Quillbolt Knight would potentially the next Yusei Fudo side monster (the way Armory Arm is right now, sorta) if it were made. I mean just look at it! Junk Synchron into Speed Warrior into Quillbolt Hedgehog into Quillbolt Knight into Junk Archer after a round with a 4000-ATK beater.

Quillbolt Knight isn't really OTK material though... the card advantage it represents is really only overwhelming with Instant Fusion, something that I made quite apparent, I hope - and an ATK-based OTK that has no field clearance involved is a weak OTK indeed.

Naturias Overload!
Normal Spell
Double the attack of "Naturia" monsters until the End Phase of this turn. During your opponent's next Standby Phase, destroy all monsters who has benefited from this card's effect.

Needs some work on the actual wording, but overall I could see this working well in a Naturia deck, mostly because of their low attack, but besides that it would be pretty bad.

Overgrowth
Counter Trap
Discard 1 "Naturia" Monster. Negate an Effect Monster's effect and remove it from play.

Wording here doesn't make much sense either. If it can negate continuous effects, then it's not a Counter Trap. Should it read "Negate the activation of an Effect Monster's effect and remove that monster from play"?

 

[Apple Juice]

Ah, I forgot the activation part. Thanks for reminding me. No it can't negate continous spells.

Magnificent Blast
Normal Spell Card
If this card is negated by an opponent's trap card, your opponent takes 1500 points of damage. Deal 1000 points of damage to your opponent, and remove this card from play. Durng your next two Standby Phases, discard 1 card to deal 1000 points of damage to your opponent.

The wording might not be top notch on this one either.

Wow lol
The damage may be a bit high, as even cards like Tremendous Fire and Meteor of Destruction have drawbacks to their activation.

I'm confused about the negation part too, since technically, that effect is negated too when the card is negated. Also most cards negate the activation not the effect so the rules say the card wasn't played at all, therefore it can't really have an effect. The only way that effect can be used is if the card's effect (not activation) is negated, but again if the effect is negated, then that part is negated too lol

Standby Phase ons is weird too but idk how to fix that.
