So I had an idea to make Televised monsters...

[spoiler=Monster]
Televised Video Tape
LIGHT / Level 3
[Machine/Effect]
Once per turn, you can Target 1 Face-up monster your Opponent controls: Target monster looses 300 ATK until the End Phase. If this card is destroyed as a result of battle, activate 1 of the following:
•Add to your Hand 1 "Televised" monster from your Deck.
•Special Summon 1 "Televised Video Tape" from your Deck.
ATK / 1600 DEF / 0

Televised Signal Feeder
LIGHT / Level 2
[Machine/Effect]
If you control a Face-up "Televised" monster, you can Special Summon this card(from your Hand). Once per turn, if this card is in Face-up Attack Position, you can select and activate 1 of the following:
•Increase the ATK of all "Televised" monsters you currently control, except "Televised Signal Feeder", by 500 until the End Phase.

ATK / 0 DEF / 0

Televised King TV

You can only activate 1 "Signal Booster" per turn, and you can only Summon "Televised" monsters during the turn you activated this effect.

Replay Channel

Trap
Tribute 1 "Televised" monster. Until the End Phase, the ATK of all Face-up monsters currently on the field becomes 0.[/spoiler]

[Scrooge]

I like these cards, especially because they mostly operate by supporting one another. I can easily see the first 2 being used in conjuction with the likes of Gravity Bind and Level Limit - Area B. Video tape can easily reach 2000 ATK, while an opponent's monster's ATK is reduced by 300. All 3 cards can assist the user to get his hand on some better cards from his deck and somewhat swarm the field; Video Tape can search when destroyed (most likely for King TV), but Signal Feeder can also be Special Summoned during Main Phase 2 immediately after being searched, which is nice. King TV can search much like Video Tape, most likely for Signal Feeder.

 

The interesting synergy would be a result of King TV and signal feeders. His ATK could as well reach the 3500-4000 range, while being a 4 level monster. What I don't understand is whether the ATK gain is permanent or not.

 

I like these cards quite a lot, and I'd like to know with what sort of supportive spells and traps in mind, you designed them.

Silly Me, I forgot the "Until the End Phase" part of King's effect.
Also I added stuff.

Decided to tweak/add some things.

Bump + added stuff
