Playtest, playtest, playtest. Get decklists of other meta/top tier decks and play against them by yourself.
Also, about the being really hard lately, either stop touching yourself, or go see a doctor.
I'm probably going to remake my one from 2008. Actually, I'm going to copy it here, and then we can critique it together.
Obviously, there are some things that need updating, but I think it's a workable start.
I'll do my newest ones, I guess.
Blue Eyes Hydra Dragon
(Level 10/LIGHT/4000/3500)
[Dragon / Synchro / Effect]
1 Tuner + 1 or more "Blue Eyes" non-Tuner monster
This card's name is treated as "Blue Eyes White Dragon" while face-up on the field or in the Graveyard. A Synchro Summoning of this card can be performed even when the combined Levels of the Synchro Material Monsters exceeds the Level of this card. When this card is Synchro Summoned, this card gains the appropriate effects, based on the number of non-Tuner Synchro Material Monsters used:
* 1 or more: Once per turn, during your En
That was so shitty I couldn't even get through the entire deck list. I get that he was trying to make a deck that didn't use cards that were post-original YGO, but even then...
Winged Kuriboh
(Level 1/LIGHT/300/200)
[Fairy / Effect]
When your opponent declares an attack while this card is on the field, you may Tribute this card to negate the attack and end your opponent's turn. This effect can be activated even while this card is face-down. When this card is Tributed, Special Summon 1 "Kuriboh" monster from your Deck in face-up Defense Position.
That's how Winged Kuriboh should have been made.
I didn't know you made an account, Swifty. Cool beans.
And I've been doing pretty well without a Vortex or a Mirror Force so far, but I'll test it out on YVD sometime before my regionals.
Nothing short of a Siricco-boosted BW or a Synchro can run over Spy. That gives me free field advantage that I can use to bring out my own Synchros (especially Arcanite Magician, which regular BWs can't bring out, and greatly enhances my potential for quick games).
Also, Spies give me a few extra targets for Allure, seeing as I wouldn't really want to use Allure on any of my Blackwings.
What do you mean? Lots of people play Blackwings, Blackwings are screwed over against Spies, I run Spies, I win more against Blackwings. What's not to get?
