Orbital Observation Satellite- isn't that effect a bit cheap, the total immunity party... o_o; usually there's some sort of catch to it.
What do you mean total immunity? Cyber Dragon and anything else above four stars eats it for breakfast, all conventional forms of monster removal smash it and piercing monsters laugh at it. I don't see what's so cheap about it.
Deflector Satellite- same as the above... Satellite cannon gets the not destroyed by battle only if it's attack mode i think (therefore takes LP damage), but these two... yeah.
Actually, Satellite Cannon is protected in defense position too. Either that or the makers of Spirit Caller got their card effects seriously messed up. o.O The original SC (Provided that we ignore the stream of destruction and theft effects against it) is only vulnerable on the turn it's summoned and the turn after it attacks so these are mimicking it. (Actually, I even took the wording for that effect from Satellite Cannon)
Seal thingymabblobber: Well, this isn't really doing squat to help Uria. Even if you
do get the poor thing out, he'll be about as useful as Slifer with an empty hand since you won't have enough continuous traps in your graveyard. =O Raviel, on the other hand, isn't really
that hard to get out. Heck, I'm pretty sure that multiplied Kuriboh would do the trick (Remember, since you're offering the tokens as tribute for a card effect it's not considered to be a tribute summon. Same as with toons and goat tokens. :3) it's just that big monsters in general don't get to stay on the field for long. Hamon gets a leg up (sort of) but the phantasms still remain a novelty imo.
Battlefield: You could just say "While this card is on the Field, neither player can declare instant victory.". That should cover it. Yay for pure, unrestrained beatdown. I could definitely see this being sided in against burn decks. :3
WMC supports: Big problem with both; Wave-Motion Cannon doesn't use counters. The effect is based on the number of your Standby Phases the cannon has been on the field, meaning that with the current wording both cards won't do anything at all. T_T
Growl of the Panther: Right...so suppose you used that panther to copy a 'can't be destroyed by battle' monster? That's a seriously powerful lock right there. x.x
Ultima Black Panther: Fair enough.
Claw of the Black Panther: Sort of a situational Sakuretsu with an added bonus, but the ability to steal an additional effect works nicely with growl over there.
Call of the Wild: Sort of more beast than panther support, but fair enough. Too bad it doesn't work with the panther's special summon, though.
Aaanyway, since the panther is a neo-spacian this calls for:
Elemental Hero Ultima Neos
Warrior/Fusion/Effect
10 Star/Dark
2500 Atk/2000 Def
"Elemental Hero Neos" + "Neo-Spacian Ultima Black Panther"
This card can only be Special Summoned from your Fusion Deck by returning the above cards from your side of the field to the Deck. (You do not use "Polymerization".) You can select 1 face-up Monster on the field if 1 is not already selected by this card. While this card is face-up on your side of the field, increase the Atk of this card by half the Atk of the selected monster. (You can select up to 1 monster at a time with this effect.). While this card is on the Field, negate the effects of all Effect Monsters on your opponent's Field. This card returns to the Fusion Deck during the End Phase.
Aaaand one more satellite:
Proto-Satellite Cannon - Lotus
Machine/Gemini
4 Star/Light
0 Atk / 2000 Def
This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is face-up on the field, you can Normal Summon it to have it be treated as an Effect Monster with this effect:
-The original Def of this card becomes zero and this card is treated as "Satellite Cannon". This card can not be destroyed in battle with a level 5 or lower monster. During each Standby Phase, increase the Atk of this card by 2000. When this card attacks, the Atk of this card returns to zero at the end of the Damage Step. During each End Phase, if the Atk of this card is 4000 or higher, the Atk of this card returns to zero.
I've also done a little revamping on Combined Fire and Energy Spike:
Energy Spike
Normal Spell
This card can only be activated when there's at least one "Satellite Cannon" on the Field. Once per turn, until your third End Phase after this card's activation, increase the Atk of each "Satellite Cannon" on the Field by 1000.
Combined Fire
Continuous Spell
Once per turn, during your Main Phase, you may pay 800 Life Points select one face-up "Satellite Cannon" on the Field. The Atk of the selected monster becomes the combined Atk of all "Satellite Cannon"s on your Field. On the turn this card is activated, the selected monster can attack every monster on your opponent's Field and only the selected monster can attack. On the End Phase of the turn when this card's effect is activated, reduce the Atk of all face-up "Satellite Cannon"s on your Field to zero.
