Only straightforward thing I saw wrong was friends. I know there's another spell card that lets you summon two monsters during one turn.

I seem to have memorized the response I'm about to give. Friends is a 10-year-old version of Double Summon. I made mine when YGO first aired in North America. I just like mine better, even though it seems EXTREMELY redundant that I posted it here.

Even if you made yours first it wouldn't make sense since there is a workable one in the game already. Approving Friends would be letting you bypass the 3 card limit.

Like anyone in their right mind would even consider running 3 Double Summon cards.

If I recall correctly, you must first post the cards. The prices here only apply assuming your cards are: A) Common and B) Unlimited Edition.


Sonic Night Dragon
Common: 1 Point
Unlimited Edition: 1 Point
Dark: 20 Points
Dragon: 5 Points
ATK/DEF: 40 Points
Effect: A Nomi with it's SS-able monster being a Vanilla. It's fine. 1 Point.
Total: 68 Points


Nightmare Sonic Blast
Common: 1 Point
Unlimited Ed.: 1 Point
Normal Spell: 20 Points
Effect: Nothing really too overwhelming about it. 3 Points.
Total: 25 Points

Red-Eyes Zombie Dragon
(NOTE: A card with this name already exists)
Common: 1 Point
Unlimited Ed.: 1 Point
Dark: 20 Points
Zombie: 10 Points
ATK/DEF: 20 Points
Effect: The orriginal Red Eyes Zombie Dragon has a much better effect. Overall, too specific an effect to do too much damage. 3 Points
Total: 55 Points

Armed Dragon Infinity
Common: 1 Point
Unlimited Ed.: 1 Point
Wind: 5 Points
Dragon: 5 Points
ATK/DEF: 40 Points
Effect: A nomi that requires a nomi that requires a nomi. 1 Point
Total: 53 Points

Darkness Desperato
Common: 1 Point
Unlimited Ed.: 1 Point
Quick Play Spell: 35 Points
Effect: Life Points don't matter until they hit zero. As far as the effect goes, it has the potential to create a lot of OTKs. Especially since dark is such an already heavily supported type. 30 points, but unlimited.
Total: 67 Points


Distant Source of Light
Common: 1 Point
Unlimited Ed.: 1 Point
Continuous Spell: 25
Effect: Does not deserve to be limited. As it pretty much maxes at + 2400 attack, but then you run the risk of monster destruction and drawing into such a useless high level card. Unless some broken RFG light type monster was created, this card should be safe at 3. 5 Points.
Totall: 32

Friends
Common: 1 Point
Unlimited Ed.: 1 Point
Normal Spell: 20
Effect: Because people really need to play 6 Double Summons in a turn. 1 Point.
Total: 23 Points

Future Summon
Common: 1 Point
Unlimited Ed.: 1 Point
Normal Spell: 20 Points
Effect: Not at all limitable. A decent card. The wait might end up destroying you however. 5 Points.
Total: 27 Points.

Typhoon
Common: 1 Point
Unlimited Ed.: 1 Point
Continuous Trap: 30 Points
Effect: It's like a worse off version of Swords of Revealing Light. 5 Points.
Total: 37 Points

Apocalypse
Counter Traps don't work that way. They have to... you know... counter something. It would probably work much better as a normal trap, and would not be limited.

I know it doesn't counter anything. I just wanted Apocalypse to have a higher Spell Speed than Normal Trap cards.

Besides, why extra points depending on rarity? It doesn't affect the gameplay one bit.
